FORWARD‑LOOKING STATEMENTS

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 including, in particular, the statements about our plans, strategies and prospects under the heading “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part I – Financial Information of this Form 10-Q. Forward-looking statements express an expectation or belief and contain a projection, plan or assumption with regard to, among other things, our future revenues, income, expenses or capital structure. Such statements of future events or performance are not guarantees of future performance and involve estimates, assumptions and uncertainties. The words “could,” “may,” “predict,” “anticipate,” “would,” “believe,” “estimate,” “expect,” “forecast,” “project,” “objective,” “intend,” “continue,” “should,” “plan,” and similar expressions, or the negatives thereof, are intended to identify forward-looking statements unless the context requires otherwise.

Some important factors that could cause our actual results or outcomes to differ materially from those discussed in the forward-looking statements include, but are not limited to:

• fluctuations in customer growth and demand;

• impacts of weather on retail sales and wholesale prices;

• impacts of renewable energy generation, natural gas prices and other market factors on wholesale prices;

• weather-related damage to our electrical system;

• fuel, commodity and other input costs;

• performance of our suppliers;

• generating unit availability and capacity;

• transmission and distribution system reliability and capacity, including natural gas pipeline system and supply constraints;

• purchased power costs and availability;

• availability and price of capacity;

• regulatory action, including, but not limited to, the review of our basic rates and charges by the IURC;

• federal and state legislation and regulations;

• changes in our credit ratings or the credit ratings of AES;  

• fluctuations in the value of pension plan assets, fluctuations in pension plan expenses and our ability to fund defined benefit pension plans;

• changes in financial or regulatory accounting policies;

• environmental matters, including costs of compliance with current and future environmental laws and requirements;

• interest rates, inflation rates and other costs of capital;

• the availability of capital;

• the ability of subsidiaries to pay dividends or distributions to IPALCO;

• level of creditworthiness of counterparties to contracts and transactions;

• labor strikes or other workforce factors, including the ability to attract and retain key personnel;

• facility or equipment maintenance, repairs and capital expenditures;

• significant delays or unanticipated cost increases associated with large construction projects;

• the availability and cost of funds to finance working capital and capital needs, particularly during periods when the time lag between incurring costs and recovery is long and the costs are material;

• local economic conditions;

• catastrophic events such as fires, explosions, cyber-attacks, terrorist acts, acts of war, pandemic events, or natural disasters such as floods, earthquakes, tornadoes, severe winds, ice or snow storms, droughts, or other similar occurrences;

• costs and effects of legal and administrative proceedings, audits, settlements, investigations and claims and the ultimate disposition of litigation;

• industry restructuring, deregulation and competition;

5

• issues related to our participation in MISO, including the cost associated with membership, allocation of costs, costs associated with transmission expansion, the recovery of costs incurred, and the risk of default of other MISO participants;

• changes in tax laws and the effects of our strategies to reduce tax payments;

• the use of derivative contracts; and

• product development, technology changes, and changes in prices of products and technologies.

All of the above factors are difficult to predict, contain uncertainties that may materially affect actual results, and many are beyond our control. See “Item 1A. Risk Factors” and “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” in IPALCO’s 2016 Form 10-K for a more detailed discussion of the foregoing and certain other factors that could cause actual results to differ materially from those reflected in any forward-looking statements. Except as required by the federal securities laws, we undertake no obligation to publicly update or review any forward-looking information, whether as a result of new information, future events or otherwise. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements.

IPALCO ENTERPRISES, INC. and SUBSIDIARIES

Notes toUnauditedCondensed Consolidated Financial Statements

1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

IPALCO is a holding company incorporated under the laws of the state of Indiana. IPALCO, acquired by AES in March 2001, is owned by AES U.S. Investments (82.35%) and CDPQ (17.65%). AES U.S. Investments is owned by AES U.S. Holdings, LLC (85%) and CDPQ (15%). IPALCO owns all of the outstanding common stock of IPL. Substantially all of IPALCO’s business consists of generating, transmitting, distributing and selling of electric energy conducted through its principal subsidiary, IPL. IPL was incorporated under the laws of the state of Indiana in 1926. IPL has approximately 490,000 retail customers in the city of Indianapolis and neighboring cities, towns and communities, and adjacent rural areas all within the state of Indiana, with 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 four generating stations, all within the state of Indiana. IPL’s largest generating station, Petersburg, is coal-fired. The second largest station, Harding Street, has converted its coal-fired units to natural gas and uses natural gas and fuel oil to power combustion turbines. In addition, IPL began the operation of a 20 MW battery energy storage unit at this location in May 2016, which provides frequency response. The third station, Eagle Valley, retired its coal-fired units in April 2016. The CCGT at Eagle Valley is expected to be completed in the first half of 2018 with a rated output of 671 MW. The fourth station, Georgetown, is a small peaking station that uses natural gas to power combustion turbines. As of June 30, 2017, IPL’s net electric generation capacity for winter is 2,996 MW and net summer capacity is 2,881 MW.

Principles of Consolidation

The accompanying 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 GAAP for interim financial information and in conjunction with the rules and regulations of the SEC. Accordingly, they do not include all of the disclosures required by GAAP 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 2016 Form 10-K and should be read in conjunction therewith.

Use of Management Estimates

The preparation of financial statements in conformity with GAAP 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

The following table provides a brief description of recent accounting pronouncements that had and/or could have a material impact on the Company’s Financial Statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on the Company’s Financial Statements.

10

New Accounting Standards Adopted
ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	The standard simplifies the following aspects of accounting for share-based payments awards: accounting for income taxes, classification of excess tax benefits on the statement of cash flows, forfeitures, statutory tax withholding requirements, classification of awards as either equity or liabilities and classification of employee taxes paid on statement of cash flows when an employer withholds shares for tax-withholding purposes. Transition method: The recognition of excess tax benefits and tax deficiencies arising from vesting or settlement were applied retrospectively. The elimination of the requirement that excess tax benefits be realized before they are recognized was adopted on a modified retrospective basis with a cumulative adjustment to the opening balance sheet.	January 1, 2017	The primary effect of adoption was the recognition of excess tax benefits in our provision for income taxes in the period when the awards vest or are settled, rather than in paid-in-capital in the period when the excess tax benefits are realized. We will continue to estimate the number of awards that are expected to vest in our determination of the related periodic compensation cost. The adoption of this standard did not have a material impact on the consolidated financial statements.
New Accounting Standards Issued But Not Yet Effective
ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities	This standard shortens the period of amortization of the premium on certain callable debt securities to the earliest call date. Transition method: modified retrospective.	January 1, 2019. Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	This standard changes the presentation of non-service cost expense associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization. Transition method: Prospective for presentation of non-service cost expense. Retrospective for the change in capitalization.	January 1, 2018. Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements and does not plan to early adopt.
2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business	This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. Transition method: prospective.	January 1, 2018. Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)	This standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Transition method: retrospective.	January 1, 2018 Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory	This standard requires that an entity recognizes the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. Transition method: modified retrospective.	January 1, 2018 Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
2016-13, Financial Instruments -Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	The standard updates the impairment model for financial assets measured at amortized cost to an expected loss model rather than an incurred loss model. It also allows for the presentation of credit losses on available-for-sale debt securities as an allowance rather than a write down. Transition method: various.	January 1, 2020 Early adoption is permitted only as of January 1, 2019.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements.
2016-02, Leases (Topic 842)	The standard creates Topic 842, Leases, which supersedes Topic 840, Leases. It introduces a lessee model that brings substantially all leases onto the balance sheet while retaining most of the principles of the existing lessor model in U.S. GAAP and aligning many of those principles with ASC 606, Revenue from Contracts with Customers. Transition method: modified retrospective approach with certain practical expedients.	January 1, 2019. Early adoption is permitted.	The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. The Company intends to adopt the standard as of January 1, 2019.
2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-05, Revenue from Contracts with Customers (Topic 606)	See discussion of this ASU below:	January 1, 2018	The Company will adopt the standard on January 1, 2018; see below for the evaluation of the impact of its adoption on the consolidated financial statements.

ASU 2014-09 and its subsequent corresponding updates provide the principles an entity must apply to measure and recognize revenue. The core principle is that an entity shall recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or

11

services. Amendments to the standard were issued that provide further clarification of the principle and to provide certain transition expedients. The standard will replace most existing revenue recognition guidance in GAAP, including the guidance on recognizing other income upon the sale or transfer of non-financial assets (including in-substance real estate).

The standard requires retrospective application and allows either a full retrospective adoption in which all of the periods are presented under the new standard or a modified retrospective approach in which the cumulative effect of initially applying the guidance is recognized at the date of initial application. We are currently working toward adopting the standard using the full retrospective method. However, the Company will continue to assess this conclusion which is dependent on the final impact to the Financial Statements.

In 2016, the Company established a cross-functional implementation team and is in the process of evaluating changes to our business processes, systems and controls to support recognition and disclosure under the new standard. At this time, we do not expect any significant impact on our financial systems as a result of the implementation of the new revenue recognition standard.

The Company is currently evaluating certain contracts along with our tariff revenue and certain revenue arrangements with MISO (i.e., capacity and wholesale agreements). The Company expects additional contracts to be executed during 2017 that will require assessment under the new standard. Through this assessment, the Company has identified certain key issues that we are continuing to evaluate in order to complete our assessment of the full population of contracts and be able to assess the overall impact to the Financial Statements. These issues include: the application of the practical expedient for measuring progress toward satisfaction of a performance obligation, when variable quantities would be considered variable consideration versus an option to acquire additional goods and services, and how to measure progress toward completion for a performance obligation that is a bundle. We are continuing to work with various non-authoritative industry groups and monitoring the FASB and Transition Resource Group (TRG) activity, as we finalize our accounting policy on these and other industry specific interpretative issues which are expected in 2017.

2. REGULATORY MATTERS

Basic Rates and Charges

In March 2016, the IURC issued the 2016 Rate Order authorizing IPL to increase its basic rates and charges by $30.8 million annually. The order also authorized IPL to collect, over a ten year period, $117.7 million of previously deferred regulatory assets related to IPL’s participation in the regional transmission organization known as MISO. Such deferred costs will be amortized to expense over ten years. Accordingly, $11.8 million of IPL’s long-term MISO regulatory asset is included within current regulatory assets on the accompanying Unaudited Condensed Consolidated Balance Sheets. The rate order also authorized an increase in IPL’s depreciation rates of $24.3 million annually compared to the twelve months ended June 30, 2014, which is the period upon which the rate increase was calculated. IPL also received approval to implement three new rate riders for current recovery from customers of ongoing MISO costs and capacity costs, and for sharing with customers 50% of wholesale sales margins above and below the established annual benchmark of $6.3 million. Additionally, the capacity rider provides that IPL will share with customers 50% of any capacity sales. The order approved recovery of IPL’s pension expenses and a return on IPL’s discretionary pension fundings. While the IURC noted in the order that they found IPL’s Service Company cost allocations to be reasonable, IPL was directed to request the FERC to review its Service Company allocations. Such review is currently underway. The IURC also closed their investigation into IPL’s underground network.

Some of the intervening parties in the IURC rate case filed petitions for reconsideration of the IURC’s March 2016 order with respect to certain issues. These petitions were subsequently denied by the IURC. In addition, certain intervening parties filed notices of appeal of the order. On April 5, 2017, the Indiana Court of Appeals affirmed the IURC’s March 2016 order.

In May 2014, IPL received an order from the IURC granting approval to build a 644 to 685 MW CCGT at Eagle Valley. The costs to build and operate the CCGT, other than fuel costs, will not be recoverable by IPL through rates until the conclusion of a base rate case proceeding with the IURC after construction is completed.

On December 22, 2016, IPL filed a petition with the IURC for authority to increase its basic rates and charges primarily to recover the cost of the new CCGT. The CCGT was previously expected to be completed in the first half of 2017, but is now expected to be completed in the first half of 2018. To address this change, on February 24, 2017, IPL filed a motion to withdraw the case without prejudice or alternatively amend the petition and case-in-chief at a later date. On March 15, 2017, the IURC dismissed the rate case without prejudice. IPL expects to file a new base rate case with the IURC to coincide with the completion of the CCGT.

12

CCR

On April 26, 2017, the IURC approved IPL’s CCR compliance request to install a bottom ash dewatering system at its Petersburg generating station and to recover 80% of qualifying costs through a rate adjustment mechanism with the remainder recorded as a regulatory asset for recovery in a subsequent rate case. The approved capital cost of the CCR compliance plan is approximately $47 million.

NAAQS

On April 26, 2017, the IURC approved IPL’s request for NAAQS SO2 compliance at its Petersburg generation station with 80% of qualifying costs recovered through a rate adjustment mechanism and the remainder recorded as a regulatory asset for recovery in a subsequent rate case. The approved capital cost of the NAAQS SO2 compliance plan is approximately $29 million.

3. FAIR VALUE

Fair Value Hierarchy

ASC 820 defined and established a framework for measuring fair value and expands 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 that are adjusted to fair value, 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; and 

Level 3 - unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.

As of June 30, 2017 and December 31, 2016, all of IPALCO’s financial assets or liabilities adjusted to fair value on a recurring basis (excluding pension assets – see Note 7, “Benefit Plans”) were considered Level 3, based on the above fair value hierarchy. These primarily consisted of FTRs, which are used to offset MISO congestion charges. Because the benefit associated with FTRs is a flow-through to IPL’s jurisdictional customers, IPL records a regulatory liability matching the value of the FTRs. 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. All of 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.

Non-Recurring Fair Value Measurements

ASC 410 “Asset Retirement and Environmental Obligations” addresses financial accounting and reporting for legal obligations associated with the retirement of long-lived assets that result from acquisition, construction, development and/or normal operation. A legal obligation for purposes of ASC 410 is an obligation that a party is required to settle as a result of an existing law, statute, ordinance, written or oral contract or the doctrine of promissory estoppel. IPL’s ARO liabilities relate primarily to environmental issues involving asbestos-containing materials, ash ponds, landfills and miscellaneous contaminants associated with its generating plants, transmission system and distribution system. We use the cost approach to determine the fair value of IPL’s ARO liabilities, which is estimated by discounting expected cash outflows to their present value at the initial recording of the liabilities. Cash outflows are based on the approximate future disposal costs as determined by market information, historical information or other management estimates. These inputs to the fair value of the ARO liabilities would be considered Level 3

13

inputs under the fair value hierarchy. As of June 30, 2017 and December 31, 2016, ARO liabilities were $80.8 million and $80.6 million, respectively. 

Financial Instruments not Measured at Fair Value in the Consolidated Balance Sheets

Debt

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. In certain circumstances, the market for such securities was inactive and therefore the valuation was adjusted to consider changes in market spreads for similar securities. Accordingly, 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 (Level 2) for the periods ending:  

	June 30, 2017				December 31, 2016
	Face Value		Fair Value		Face Value		Fair Value
	(In Millions)
Fixed-rate	$	2,438.5	$	2,622.1	$	2,438.5	$	2,543.5
Variable-rate	198.5		198.5		140.0		140.0
Total indebtedness	$	2,637.0	$	2,820.6	$	2,578.5	$	2,683.5

The difference between the face value and the carrying value of this indebtedness represents the following:

• unamortized deferred financing costs of $20.8 million and $22.2 million at June 30, 2017 and December 31, 2016, respectively; and

• unamortized discounts of $6.6 million and $6.8 million at June 30, 2017 and December 31, 2016, respectively.

4. EQUITY

On March 1, 2016, IPALCO issued and sold 7,403,213 shares of IPALCO’s common stock to CDPQ for $134.3 million under the Subscription Agreement. After completion of these transactions, CDPQ’s direct and indirect interests in IPALCO total approximately 30%. On June 1, 2016, IPALCO received equity capital contributions of $64.8 million from AES U.S. Investments and $13.9 million from CDPQ. IPALCO then made the same investments in IPL. The proceeds were primarily used for funding needs related to IPL’s environmental and replacement generation projects. The capital contributions on June 1, 2016 were made on a proportional share basis and, therefore, did not change CDPQ’s or AES’ ownership interests in IPALCO.

IPL First Mortgage Bonds

On August 1, 2017, IPL repaid $24.7 million in outstanding borrowings of 5.40% IPL first mortgage bonds that were due in August 2017.

IPALCO’s Senior Secured Notes

IPALCO has $400 million of 5.00% Senior Secured Notes due May 1, 2018. Although current liquid funds are not sufficient to pay these notes at maturity, we believe that we will be able to refinance these notes based on our conversations with investment bankers, which currently indicate more than adequate demand for new IPALCO debt at our current credit rating; and the previous successful issuance of our $405 million IPALCO senior secured notes in 2015, which served to refinance existing notes. Should the capital markets not be accessible to IPALCO at the time of the maturity of the 2018 IPALCO Notes, management believes that other financing options are at its disposal to meet the needs of the maturity.

Line of Credit

As of June 30, 2017 and December 31, 2016, IPL had $108.5 million and $50.0 million in outstanding borrowings on the committed line of credit, respectively.

6. INCOME TAXES

IPALCO’s effective combined state and federal income tax rates were 32.0% and 31.9% for the three and six months ended June 30, 2017, respectively, as compared to 33.3% and 33.0% for the three and six months ended June 30, 2016, respectively. The decrease in the effective tax rates versus the comparable periods was primarily due to the manufacturer’s production deduction (Internal Revenue Code Section 199) that had been previously limited due to a Net Operating Loss carryover.

7. BENEFIT PLANS

The following table (in thousands) presents information for the six months ended June 30, 2017, relating to the Pension Plans:

(1) Amounts that would otherwise be charged/credited to Accumulated Other Comprehensive Income or Loss upon application of ASC 715, “Compensation – Retirement Benefits,” are recorded as a regulatory asset or liability because IPL has historically recovered and currently recovers pension and other postretirement benefit expenses in rates. These are unrecognized amounts not yet recognized as components of net periodic benefit costs.

(2) The settlement loss of $0.1 million for the three months ended March 31, 2017 was the result of a lump sum distribution paid out of the Supplemental Retirement Plan.

In addition, IPL provides postretirement health care benefits to certain active or retired employees and the spouses of certain active or retired employees. These postretirement health care benefits and the related unfunded obligation of $7.1 million and $6.8 million at June 30, 2017 and December 31, 2016, respectively, were not material to the Financial Statements in the periods covered by this report.

8. 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 and 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.

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 be certain that we have been or will be at all times in full compliance with such laws, regulations and permits.

New Source Review and Other CAA NOVs

In October 2009, IPL received a NOV and Finding of Violation from the EPA pursuant to the CAA Section 113(a). The NOV alleges violations of the CAA at IPL’s three primarily coal-fired electric generating facilities at the time, dating back to 1986. The alleged violations primarily pertain to the PSD and nonattainment New Source Review requirements under the CAA. In addition, on October 1, 2015, IPL received a NOV from the EPA pursuant to CAA Section 113(a) alleging violations of the CAA, the Indiana SIP, and the Title V operating permit related to alleged particulate matter and opacity violations at IPL Petersburg Unit 3. Also, on February 5, 2016, the EPA issued a NOV pursuant to CAA Section 113(a) alleging violations of New Source Review and other CAA regulations, the Indiana SIP, and the Title V operating permit at Petersburg Generating Station. Since receiving the letters, IPL management has met with the EPA staff regarding possible resolutions of the NOVs. Settlements and litigated outcomes of similar New Source Review 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 these cases could have a material impact on our business. It is too early to determine whether these NOVs could have a material impact on our business, financial condition or results of operations. We would seek recovery of any operating or capital expenditures, but not fines or penalties, related to air pollution control

18

technology to reduce regulated air emissions; however, there can be no assurances that we would be successful in this regard. IPL has recorded a contingent liability related to these New Source Review cases and other CAA NOV matters.

9. SEGMENT INFORMATION

Operating segments are components of an enterprise that engage in business activities from which it may earn revenues and incur expenses, 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 segment is its utility segment, with all other non-utility business activities aggregated separately. The non-utility category primarily includes the 2018 IPALCO Notes and the 2020 IPALCO Notes; approximately $12.6 million and $8.3 million of cash and cash equivalents, as of June 30, 2017 and December 31, 2016, respectively; long-term investments of $4.9 million and $5.2 million at June 30, 2017 and December 31, 2016, respectively; and income taxes and interest related to those items. All other assets represented less than 1% of IPALCO’s total assets as of June 30, 2017 and December 31, 2016. Net income for the utility segment was $61.7 million and $70.1 million for the six-month periods ended June 30, 2017 and 2016, respectively, and $29.4 million and $36.4 million for the three-month periods ended June 30, 2017 and 2016, respectively. The accounting policies of the identified segment 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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the Financial Statements and the notes thereto included in “Item 1. Financial Statements” included in Part I – Financial Information of this Form 10-Q. The following discussion contains forward-looking statements. Our actual results may differ materially from the results suggested by these forward-looking statements. Please see “Forward–Looking Statements” at the beginning of this Form 10-Q.

RESULTS OF OPERATIONS

The electric utility business is affected by seasonal weather patterns throughout the year and, therefore, operating revenues and associated expenses are not generated evenly by month during the year. 

Comparison of three months ended June 30,2017 and three months ended June 30,2016

Utility Operating Revenues

Utility operating revenues during the three months ended June 30,2017decreased by $1.5 million compared to the same period in 2016, which resulted from the following changes (dollars in thousands):

	Three Months Ended
	June 30,							Percentage
	2017		2016		Change			Change
Utility operating revenues:
Retail revenues	$	314,453	$	314,105	$	348		0.1%
Wholesale revenues	1,802		3,012		(1,210		)	(40.2)%
Miscellaneous revenues	5,570		6,172		(602		)	(9.8)%
Total utility operating revenues	$	321,825	$	323,289	$	(1,464	)	(0.5)%
Heating degree days:
Actual	355		508		(153		)	(30.1)%
30-year average	503		499
Cooling degree days:
Actual	314		401		(87		)	(21.7)%
30-year average	332		343

The increase in retail revenues of $0.3 million was primarily due to (i) a net increase in the weighted average price per kWh sold ($9.5 million); partially offset by (ii) a 3% decrease in the volume of kWh sold ($5.4 million) and (iii) the one-time impact in the prior period of recognizing in IPL’s unbilled revenue calculation the increase in IPL’s base rates relating to revenues that were previously charged through IPL’s environmental cost recovery rate adjustment mechanism, or rider ($3.8 million). The $9.5 million increase in the weighted average price of retail kWh sold was primarily due to: (i) a $5.1 million increase in billings for the MISO, Capacity, and Off System Sales riders(see Note 2, “Regulatory Matters” to the Financial Statements), (ii) an increase in fuel revenues of $3.4 million, (iii) a $2.2 million increase in DSM program rate adjustment mechanism revenues and (iv) other favorable retail rate variances; partially offset by (v) a $4.5 million decrease related to environmental rate adjustment mechanism revenues. The $2.2 million increase in DSM revenues is primarily related to a $4.5 million increase in our estimate of performance incentives earned in 2016, which was recorded in the second quarter of 2017, partially offset by a decrease in recoverable expenses. The majority of the decrease in environmental rate adjustment mechanism revenues is offset by decreased operating expenses, including depreciation and amortization. The $5.4 million decrease in the volume of kWh sold was primarily due to unfavorable temperatures in our service territory during the second quarter of 2017 versus the comparable period (as demonstrated by the 30% decrease in heating degree days and 22% decrease in cooling degree days, as shown above).

20

The decrease in wholesale revenues of $1.2 million was primarily due to (i) a 35% decrease in the quantity of kWh sold ($1.0 million) as IPL’s generation units were called upon by MISO to produce electricity less often during the second quarter of 2017 compared to the second quarter of 2016, largely due to unfavorable prices and unit availability; and (ii) an 8% decrease in the weighted average price per kWh sold ($0.2 million). We sold 55.6 million kWh during the second quarter of 2017 compared to 85.2 million kWh during the second quarter of 2016. Our ability to be dispatched in the MISO market is primarily driven by the locational marginal price of electricity and variable generation costs. The amount of electricity available for wholesale sales is impacted by our retail load requirements, generation capacity and unit availability. Our goal is to make wholesale sales when it is profitable to do so. Currently, 50% of IPL’s wholesale margins above and below an established annual benchmark of $6.3 million are shared with our customers through a rate rider.

Utility Operating Expenses

The following table illustrates our primary operating expense changes from the three months ended June 30,2016 to the three months ended June 30,2017 (dollars in millions):

Operating expenses for the three months ended June 30, 2016	$	279.0
Increase in fuel costs	9.6
Decrease in depreciation and amortization costs	(7.1		)
Increase in power purchased	7.1
Decrease in income taxes - net	(3.2		)
Decrease in DSM program costs	(2.3		)
Other miscellaneous variances - individually immaterial	(0.5		)
Operating expenses for the three months ended June 30, 2017	$	282.6

The $9.6 million increase in fuel costs was primarily due to (i) a $17.6 million increase in deferred fuel costs, which includes the one-time impact of $14.2 million in the prior period of recognizing in IPL’s deferred fuel calculation the increase in base rates relating to fuel revenues that were previously charged through a rate adjustment mechanism or rider, and (ii) a $3.3 million increase due to the higher price of natural gas we consumed versus the comparable period; partially offset by (iii) a $9.3 million decrease in the quantity of fuel consumed versus the comparable period and (iv) a $2.2 million decrease due to the lower price of coal we consumed versus the comparable period. We are generally permitted to recover underestimated fuel and purchased power costs to serve our retail customers in future rates through quarterly FAC proceedings. These variances are deferred when incurred and amortized into expense in the same period that our rates are adjusted to reflect these variances.

The decrease in depreciation and amortization costs of $7.1 million was primarily due to a $4.2 million decrease in regulatory deferrals and amortizations related to environmental projects, and the impact of the retirements of coal assets at our Eagle Valley and Harding Street locations during the second quarter of 2016.

The $7.1 million increase in purchased power costs was primarily due to a 30% increase in the volume of power purchased during the period ($10.4 million), partially offset by a 9% decrease in the market price of purchased power ($4.3 million). The volume of power we purchase each period is primarily influenced by our retail demand, generating unit capacity and outages, and the fact that at times it is less expensive for us to buy power in the market than to produce it ourselves. The market price of purchased power is influenced primarily by changes in the market price of delivered fuel (primarily natural gas), the price of environmental emissions allowances, the supply of and demand for electricity, and the time of day in which power is purchased.

The $3.2 million decrease in income taxes - net was primarily due to the tax effect of the decrease in pretax net operating income.

The decrease in DSM program costs of $2.3 million, which are included in “Other operating expenses” on our Unaudited Condensed Consolidated Statements of Operations and are recoverable through customer rates, is due to timing differences in spending patterns. This decrease is correlated to the decrease in DSM rate adjustment mechanism revenues excluding the change in estimated performance incentives described previously.

Other Income and Deductions

Other income and deductions increased $0.4 million, from income of $9.3 million for the three months ended June 30, 2016, to income of $9.7 million for the same period in 2017. The increase was primarily due to an increase in the income tax benefit of $0.6 million, which was primarily due to the change in pretax nonoperating income during the comparable periods.

Interest and Other Charges

Interest and other charges increased $1.8 million during the three months ended June 30,2017 compared to the same period in the prior year, primarily due to higher interest of $1.9 million on long-term debt as a result of IPL’s first mortgage bonds debt issuances of $350 million (4.05% Series, due May 2046) in May 2016.

Comparison of six months ended June 30, 2017 and six months ended June 30, 2016

Utility Operating Revenues

Utility operating revenues during the six months ended June 30, 2017increased by $7.7 million compared to the same period in 2016, which resulted from the following changes (dollars in thousands):

	Six Months Ended
	June 30,							Percentage
	2017		2016		Change			Change
Utility operating revenues:
Retail revenues	$	643,041	$	635,873	7,168			1.1%
Wholesale revenues	4,374		3,788		586			15.5%
Miscellaneous revenues	11,319		11,373		(54		)	(0.5)%
Total utility operating revenues	$	658,734	$	651,034	$	7,700		1.2%
Heating degree days:
Actual	2,559		2,971		(412		)	(13.9)%
30-year average	3,283		3,250
Cooling degree days:
Actual	316		401		(85		)	(21.2)%
30-year average	335		343

The increase in retail revenues of $7.2 million was primarily due to a net increase in the weighted average price per kWh sold ($24.9 million), partially offset by a 4% decrease in the volume of kWh sold ($13.9 million) and the one-time impact in the prior period of recognizing in IPL’s unbilled revenue calculation the increase in IPL’s base rates relating to revenues that were previously charged through IPL’s environmental cost recovery rate adjustment mechanism, or rider ($3.8 million). While billed through a rider, such revenues relating to environmental cost recovery were not includable in our unbilled calculation. The $24.9 million increase in the weighted average price of retail kWh sold was primarily due to: (i) a $10.8 million increase in billings for the MISO, Capacity, and Off System Sales riders, which took effect as part of the 2016 Rate Order (see Note 2, “Regulatory Matters” to the Financial Statements), (ii) the impact of implementing the 2016 Rate Order (see Note 2, “Regulatory Matters” to the Financial Statements), (iii) a $5.8 million increase related to environmental rate adjustment mechanism revenues, (iv) an increase in DSM program rate adjustment mechanism revenues of $2.6 million and (v) a $2.2 million increase in fuel revenues. The $2.6 million increase in DSM revenues is primarily related to a $4.5 million increase in our estimate of performance incentives earned in 2016, which was recorded in the second quarter of 2017, partially offset by a decrease in recoverable expenses. The majority of the increases in environmental rate adjustment mechanism revenues are offset by increased operating expenses, including depreciation and amortization. The $13.9 million decrease in the volume of kWh sold was primarily due to unfavorable temperatures in our service territory during the first half of 2017 versus the comparable period (as demonstrated by the 14% decrease in heating degree days and 21% decrease in cooling degree days, as shown above).

22

The increase in wholesale revenues of $0.6 million was primarily due to (i) a 13% increase in the quantity of kWh sold ($0.5 million) as IPL’s generation units were called upon by MISO to produce electricity more often during the first half of 2017 compared to the first half of 2016, largely due to favorable prices and unit availability; and (ii) a 2% increase in the weighted average price per kWh sold ($0.1 million). We sold 141.2 million kWh during the first half of 2017 compared to 125.3 million kWh during the first half of 2016. Our ability to be dispatched in the MISO market is primarily driven by the locational marginal price of electricity and variable generation costs. The amount of electricity available for wholesale sales is impacted by our retail load requirements, generation capacity and unit availability. Our goal is to make wholesale sales when it is profitable to do so. Currently, 50% of IPL’s wholesale margins above and below an established annual benchmark of $6.3 million are shared with our customers through a rate rider.

Utility Operating Expenses

The following table illustrates our primary operating expense changes from the six months ended June 30, 2016 to the six months ended June 30, 2017 (dollars in millions):

Operating expenses for the six months ended June 30, 2016	$	566.5
Increase in fuel costs	13.8
Increase in non-purchased power MISO costs	8.9
Decrease in depreciation and amortization costs	(7.8		)
Increase in power purchased	3.7
Decrease in income taxes - net	(3.7		)
Decrease in DSM program costs	(1.8		)
Other miscellaneous variances - individually immaterial	(2.3		)
Operating expenses for the six months ended June 30, 2017	$	577.3

The $13.8 million increase in fuel costs was primarily due to (i) a $15.1 million increase in deferred fuel costs, which includes the one-time impact of $14.2 million in the prior period of recognizing in IPL’s deferred fuel calculation the increase in base rates relating to fuel revenues that were previously charged through a rate adjustment mechanism or rider, and (ii) a $6.6 million increase due to the higher price of natural gas we consumed versus the comparable period; partially offset by (iii) a $4.9 million decrease due to the lower price of coal we consumed versus the comparable period and (iv) a $2.7 million decrease in the quantity of fuel consumed versus the comparable period. We are generally permitted to recover underestimated fuel and purchased power costs to serve our retail customers in future rates through quarterly FAC proceedings. These variances are deferred when incurred and amortized into expense in the same period that our rates are adjusted to reflect these variances.

MISO non-purchased power costs increased $8.9 million, which includes both current period costs and the amortization of previously deferred costs, which were included in IPL’s customer billing rates beginning April 1, 2016. Such costs were deferred as a regulatory asset prior to April 1, 2016, and are now being amortized to expense over a ten-year period.

The decrease in depreciation and amortization costs of $7.8 million was primarily due to a $5.4 million decrease in regulatory deferrals and amortization related to environmental projects, and the impact of the retirements of coal assets at our Eagle Valley and Harding Street locations during the second quarter of 2016.

The $3.7 million increase in purchased power costs was primarily due to a 12% increase in the market price of purchased power ($11.7 million) and an increase in MISO non-fuel market participation costs ($3.9 million), partially offset by a 16% decrease in the volume of power purchased during the period ($13.5 million). The volume of power we purchase each period is primarily influenced by our retail demand, generating unit capacity and outages, and the fact that at times it is less expensive for us to buy power in the market than to produce it ourselves. The market price of purchased power is influenced primarily by changes in the market price of delivered fuel (primarily natural gas), the price of environmental emissions allowances, the supply of and demand for electricity, and the time of day in which power is purchased. The MISO non-fuel market participation costs, which include both current period costs and amortization of previously deferred costs, were included in IPL’s customer billing rates beginning April 1, 2016. Such costs were deferred as a regulatory asset prior to April 1, 2016, and are now being amortized to expense over a ten-year period.

The $3.7 million decrease in income taxes - net was primarily due to the tax effect of the decrease in pretax net operating income.

23

The decrease in DSM program costs of $1.8 million, which are included in “Other operating expenses” on our Unaudited Condensed Consolidated Statements of Operations and are recoverable through customer rates, is due to timing differences in spending patterns. This decrease is correlated to the decrease in DSM rate adjustment mechanism revenues excluding the change in estimated performance incentives described previously.

Other Income and Deductions

Other income and deductions increased $1.1 million, from income of $18.5 million for the six months ended June 30, 2016, to income of $19.6 million for the same period in 2017. The increase was primarily due to an increase in the income tax benefit of $0.9 million, which was primarily due to the change in pretax nonoperating income during the comparable periods.

Interest and Other Charges

Interest and other charges increased $4.8 million during the six months ended June 30, 2017 compared to the same period in the prior year, primarily due to higher interest of $4.9 million on long-term debt as a result of IPL’s first mortgage bonds debt issuances of $350 million (4.05% Series, due May 2046) in May 2016.

KEY TRENDS AND UNCERTAINTIES

During the remainder of 2017 and beyond, we expect that our financial results will be driven primarily by retail demand, weather, generating unit availability, outage costs and, to a lesser extent, wholesale prices. In addition, IPL’s financial results will likely be driven by many other factors including, but not limited to, the following:

• rate case outcomes;

• the timely completion of major construction projects and recovery of capital expenditures through base rate growth; and

• the passage of new legislation, implementation of regulations or other changes in regulation.

If favorable outcomes related to these factors do not occur, or if the challenges described below and elsewhere in this section impact us more significantly than we currently anticipate, or if commodities move unfavorably, then these adverse factors (or other adverse factors unknown to us) may impact our operating margin, net income and cash flows. We continue to monitor our operations and address challenges as they arise. For a discussion of the risks related to our business, see “Item 1. Business” and “Item 1A. Risk Factors” as described in IPALCO’s 2016 Form 10-K.

Regulatory and Environmental

Please see Note 2, “Regulatory Matters” to the Financial Statements for an update on regulatory matters. We also are subject to numerous environmental laws and regulations in the jurisdictions in which we operate. We face certain risks and uncertainties related to these environmental laws and regulations, including existing and potential GHG legislation or regulations, and actual or potential laws and regulations pertaining to water discharges, waste management (including disposal or beneficial reuse of CCR) and certain air emissions, such as SO₂, NO_x, particulate matter and mercury. Such risks and uncertainties could result in increased capital expenditures or other compliance costs which could have a material adverse effect on our consolidated results of operations. Please see Note 8, “Commitments and Contingencies” to the Financial Statements for a description of certain environmental matters. In addition, the following discussion of the impact of environmental laws and regulations on the Company updates the discussion provided in “Item 1. Business - Regulatory Matters” and “Item 1. Business - Environmental Matters” in IPALCO’s 2016 Form 10-K.

Climate Change Legislation and Regulation

We refer to the discussion in “Item 1. Business - Environmental Matters - Climate Change Legislation and Regulation” in IPALCO’s 2016 Form 10-K for a discussion of certain recent developments, including the EPA’s CO₂ emissions rules for new electric generating units, or GHG NSPS, as well as the CO₂ emissions rules for existing power plants, called the CPP. Both the GHG NSPS and the CPP are being challenged by several states and industry groups in the D.C. Circuit. The challenges to the CPP have been fully briefed and argued but oral arguments have not yet taken place on the GHG NSPS. On March 28, 2017, the EPA filed a motion in the D.C. Circuit to hold the challenges to both the CPP and the GHG NSPS in abeyance in light of an Executive Order signed the same day. On April 28, 2017, the D.C. Circuit issued orders holding the challenges to both rules in abeyance for 60 days. The Executive Order instructs the EPA Administrator to review the GHG NSPS and CPP and “if appropriate...as soon as practicable...publish for notice and comment proposed rules suspending, revising, or rescinding those

24

rules.” On April 4, 2017, the EPA published a notice in the Federal Register to announce that it is initiating administrative reviews of both the CPP and the GHG NSPS as a result of the Executive Order.

We cannot predict at this time the likely outcome of the EPA’s review of either the CPP or the GHG NSPS. By order of the U.S. Supreme Court, the CPP has been stayed pending resolution of the challenges to the rule. Due to the future uncertainty of the CPP, we cannot at this time determine the impact on our operations or consolidated financial results, but we believe the cost to comply with the CPP, should it be upheld and implemented in its current or a substantially similar form, could be material. The GHG NSPS remains in effect at this time, and, absent further action from the EPA that rescinds or substantively revises the NSPS, it could impact any Company plans to construct and/or modify or reconstruct electric generating units in some locations, which may have a material impact on our business, financial condition or results of operations.

Environmental Wastewater Requirements

As further discussed in “Item 1. Business - Environmental Matters - Environmental Wastewater Requirements” in IPALCO’s 2016 Form 10-K, the EPA and the Army Corps of Engineers jointly published a final rule in June 2015 defining federal jurisdiction over waters of the United States. This rule, which became effective in August 2015, may expand or otherwise change the number and types of waters or features subject to federal permitting. In October 2015, the U.S. Court of Appeals for the Sixth Circuit (the “Sixth Circuit”) issued an order to temporarily stay the “Waters of the United States” rule nationwide while that court determines whether it has authority to hear the challenges that had been brought by multiple states against the rule. As of July 2017, the Sixth Circuit’s stay remains in place, while that court’s February 2016 decision that challenges to the rule belong in the appellate courts is being appealed to the U.S. Supreme Court, which court agreed in January 2017 to hear this challenge. On March 6, 2017, the EPA and the Army Corps of Engineers published in the Federal Register a notice of intent to review and rescind or revise the “Waters of the United States” rule, as required by an Executive Order signed that same day. In June 2017, the EPA and the Army Corps of Engineers jointly announced they would issue a proposed rule rescinding the term “waters of the United States.” This proposed rule, which was published in the Federal Register on July 27, 2017, indicated that the agencies would pursue a separate notice and comment rulemaking to evaluate and replace the definition. We cannot predict the outcome of this regulatory and judicial process but, if the EPA is unsuccessful in replacing the June 2015 final rule, it could have a material impact on our business, financial condition or results of operations.

In November 2015, the EPA published its final ELG rule to reduce toxic pollutants discharged into waterways by power plants. In addition to the wastewater treatment technologies being installed and operated for compliance with the requirements of the October 2012 NPDES permit described above, the final ELG rule will require closed loop or dry bottom ash handling at Petersburg. The compliance date may be as early as November 2018 or as late as December 2023, and is subject to the discretion of IDEM. IPL plans to install a dry bottom ash handling system in response to the CCR rule described above in advance of the ELG compliance date. As such, the impact of the ELG rule is not expected to be material. Industry groups have filed challenges to the ELG rule, which are pending before the U.S. Court of Appeals for the Fifth Circuit (the “Fifth Circuit”). Environmental groups have moved to intervene in these cases on behalf of the EPA. On April 24, 2017, the Fifth Circuit granted the EPA’s request to hold these challenges in abeyance during review of the rule and possible rulemaking. The Trump administration issued a stay of the ELG rule, which stay was published in the Federal Register on April 25, 2017. On May 3, 2017, environmental groups filed legal challenges to the stay. On June 6, 2017, EPA published a proposed rule for notice and comment to stay certain compliance dates of the ELG.

NAAQS

Please see Note 2, “Regulatory Matters” to the Financial Statements for further details.

Other

On April 13, 2017, as directed by President Trump’s Executive Order 13777, the EPA published a proposed rule called “Evaluation of Existing Regulations,” announcing the formation of a task force to evaluate regulatory burdens and soliciting comments on any federal regulations that should be considered for repeal, replacement, or modification. The task force will attempt to identify regulations that (a) eliminate jobs or inhibit job creation; (b) are outdated, unnecessary, or ineffective; (c) impose costs that exceed benefits; (d) create a serious inconsistency or otherwise interfere with regulatory reform initiatives and policies; (e) are based on data or methods that are not transparent or publicly available; and (f) are derived from or im

25

plement executive orders that have been rescinded or modified. It is unclear what impact this regulatory evaluation will have on our business.

In addition, on July 20, 2017, the Maryland Department of the Environment notified the EPA that it was considering suing the EPA for failing to address its November 2016 CAA petition for such federal agency to determine that 36 electric generating units in five upwind states, including two Petersburg units, emit pollutants that contribute to non-attainment of NAAQS for ozone in Maryland, as described further in IPALCO’s 2016 Form 10-K. If this petition is granted or a suit is filed and decided favorably to the Maryland Department of the Environment, our facilities could be subject to additional requirements. We would seek recovery of any capital expenditures; however, there is no guarantee we would be successful in this regard.

CAPITAL RESOURCES AND LIQUIDITY

Overview

As of June 30, 2017, we had unrestricted cash and cash equivalents of $26.9 million and available borrowing capacity of $141.5 million under our $250 million unsecured revolving credit facility after accounting for outstanding borrowings and existing letters of credit. All of IPL’s long-term borrowings must first be approved by the IURC and the aggregate amount of IPL’s short-term indebtedness must be approved by the FERC. We have approval from FERC to borrow up to $500 million of short-term indebtedness outstanding at any time through July 27, 2018. In December 2015, we received an order from the IURC granting us authority through December 31, 2018 to, among other things, issue up to $650 million in aggregate principal amount of long-term debt and refinance up to $196.5 million in existing indebtedness. As of June 30, 2017, we have $106.5 million of total debt issuance authority remaining under this order. This order also grants us authority to have up to $500 million of long-term credit agreements and liquidity facilities outstanding at any one time, of which $250 million remains available under the order as of June 30, 2017. As an alternative to the sale of all or a portion of $65 million in principal of the long-term debt mentioned above, we have the authority to issue up to $65 million of new preferred stock, all of which authority remains available under the order as of June 30, 2017. We also have restrictions on the amount of new debt that may be issued due to contractual obligations of AES and by financial covenant restrictions under our existing debt obligations. We do not believe such restrictions will be a limiting factor in our ability to issue debt in the ordinary course of prudent business operations.

We believe that existing cash balances, cash generated from operating activities and borrowing capacity on our committed credit facility will be adequate for the foreseeable future to meet anticipated operating expenses, interest expense on outstanding indebtedness, recurring capital expenditures and to pay dividends to AES U.S. Investments and CDPQ. Sources for principal payments on outstanding indebtedness and nonrecurring capital expenditures are expected to be obtained from: (i) existing cash balances; (ii) cash generated from operating activities; (iii) borrowing capacity on our committed credit facility; and (iv) additional debt financing.

IPALCO’s Senior Secured Notes

IPALCO has classified its outstanding $400 million of Senior Secured Notes due May 1, 2018 as short-term debt. For further discussion, please see Note 5, “Debt - IPALCO's Senior Secured Notes.”

Capital Requirements

Capital Expenditures

Our construction program is composed of capital expenditures necessary for prudent utility operations and compliance with environmental laws and regulations, along with discretionary investments designed to replace aging equipment or improve overall performance. Construction expenditures during the first six months of 2017 and 2016 were financed primarily with internally generated cash provided by operations, borrowings on our credit facility, long-term borrowings and equity capital contributions.

Our capital expenditure program, including development and permitting costs, for the three-year period from 2017 through 2019 is currently estimated to cost approximately $550 million (excluding environmental compliance and replacement generation costs). It includes approximately $314 million for additions, improvements and extensions to transmission and distribution lines, substations, power factor and voltage regulating equipment, distribution transformers and street lighting facilities. The capital expenditure program also includes approximately $171 million for power plant-related projects and $65 million for other miscellaneous equipment.

IPL also plans to spend a total of $655 million (of which $601 million has been expended through June 30, 2017) on replacement generation costs through 2017 as a result of the retirement of existing facilities not equipped with advanced environmental control technologies required to comply with existing and expected regulations. The balance of $54 million is projected to be expended in 2017 and 2018. Please see “Item 1. Business - Environmental Matters - Unit Retirements and Replacement Generation” as described in IPALCO’s 2016 Form 10-K for more details.

Other environmental expenditures include costs for compliance with the NPDES permit program under the CWA. The costs for NPDES at our Petersburg station for 2017 are expected to be $37 million (of which $12 million has been expended through June 30, 2017). IPL plans to spend a total of $224 million for this project (of which $199 million has been expended through June 30, 2017). Please see “Item 1. Business - Environmental Matters - Environmental Wastewater Requirements” as described in IPALCO’s 2016 Form 10-K for more details.

IPL also has projects underway related to environmental compliance for CCR and NAAQS SO2. The costs for these projects in the 2017 through 2019 forecast are expected to be $42 million. IPL plans to spend a total of $76 million for these projects (of which $43 million has been expended through June 30, 2017). Please see “Item 1. Business - Environmental Matters - Waste Management and CCR” and “Item 1. Business - Environmental Matters - NAAQS” as described in IPALCO’s 2016 Form 10-K for more details.

Other environmental capital spending for the period 2017 through 2019 includes spending for studies related to cooling water intake requirements in sections 316(a) and 316(b) of the CWA, NAAQS Ozone and Office of Surface Mining totaling $24 million. Please see “Item 1. Business - Environmental Matters - Cooling Water Intake Regulations” as described in IPALCO’s 2016 Form 10-K for more details.

Credit Ratings

Our ability to borrow money or to refinance existing indebtedness and the interest rates at which we can borrow money or refinance existing indebtedness are affected by our credit ratings. In addition, the applicable interest rates on IPL’s Credit Agreement and other unsecured notes (as well as the amount of certain other fees in the Credit Agreement) are dependent upon the credit ratings of IPL. Downgrades in the credit ratings of AES could result in IPL’s and/or IPALCO’s credit ratings being downgraded. Any reduction in our debt or credit ratings may adversely affect the trading price of our outstanding debt securities.

(a) Ratings relate to IPALCO’s Senior Secured Notes

(b) Ratings relate to IPL’s Senior Secured Bonds.

We cannot predict whether our current debt and credit ratings or the debt and credit ratings of IPL will remain in effect for any given period of time or that one or more of these ratings will not be lowered or withdrawn entirely by a rating agency. A security rating is not a recommendation to buy, sell or hold securities. Such ratings may be subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be evaluated independently of any other rating.

Dividend Distributions

All of IPALCO’s outstanding common stock is held by AES U.S. Investments and CDPQ. During the first six months of 2017 and 2016, IPALCO paid $50.1 million and $52.3 million, respectively, in dividends to its shareholders. Future distributions to our shareholders will be determined at the discretion of our Board of Directors and will depend primarily on dividends received from IPL. Dividends from IPL are affected by IPL’s actual results of operations, financial condition, cash flows, capital requirements, regulatory considerations, and such other factors as IPL’s Board of Directors deems relevant.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK 

There have been no material changes to our quantitative and qualitative disclosure about market risk as previously disclosed in the 2016 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures.

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, of the effectiveness of our “disclosure controls and procedures” (as defined in the Exchange Act Rules 13a-15(e) and 15-d-15(e)), as required by paragraph (b) of the Exchange Act Rules 13a-15 or 15d-15, as of June 30, 2017. Our management, including the principal executive officer and principal financial officer, is engaged in a comprehensive effort to review, evaluate and improve our controls; however, management does not expect that our disclosure controls or our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may become inadequate in future periods because of changes in business conditions, or that the degree of compliance with the policies or procedures deteriorates. We have interests in certain unconsolidated entities. As we do not control or manage these entities, our disclosure controls and procedures with respect to such entities is generally more limited than those we maintain with respect to our consolidated subsidiaries. 

29

Based upon the controls evaluation performed, the principal executive officer and principal financial officer have concluded that as of June 30, 2017, our disclosure controls and procedures were effective to provide reasonable assurance that material information relating to us and our consolidated subsidiaries is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to the principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Controls

In the course of our evaluation of disclosure controls and procedures, management considered certain internal control areas in which we have made and are continuing to make changes to improve and enhance controls. Based upon that evaluation, the principal executive officer and principal financial officer concluded that there were no changes in our internal controls over financial reporting identified in connection with the evaluation required by paragraph (d) of the Exchange Act Rules 13a-15 or 15d-15 that occurred during the three months ended June 30,2017 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PARTII– OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the normal course of business, we are subject to various lawsuits, actions, claims, and other proceedings. We are also from time to time involved in other reviews, investigations and proceedings by governmental and regulatory agencies regarding our business, certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief. We have accrued in our Financial Statements for litigation and claims where it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. We believe the amounts provided in our Financial Statements, as prescribed by GAAP, for these matters are adequate in light of the probable and estimable contingencies. However, there can be no assurances that the actual amounts required to satisfy alleged liabilities from various legal proceedings, claims and other matters (including those matters noted below), and to comply with applicable laws and regulations will not exceed the amounts reflected in our Financial Statements. As such, costs, if any, that may be incurred in excess of those amounts provided for in our Financial Statements cannot be reasonably determined, but could be material.

Please see Note 2, “Regulatory Matters” and Note 8, “Commitments and Contingencies” to the Financial Statements included in Part I - Financial Information of this Form 10-Q for a summary of certain legal proceedings involving us. In addition, our Form 10-K for the fiscal year ended December 31, 2016 and Form 10-Q for the quarter ended March 31, 2017, and the Notes to the Financial Statements included therein, contain descriptions of certain legal proceedings in which we are or were involved.
