Overview and Summary of Significant Accounting Policies | 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 more than 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. Our largest generating station, Petersburg, is coal-fired. The second largest station, Harding Street, uses natural gas and fuel oil to power combustion turbines. In addition, IPL operates a 20 MW battery energy storage unit at this location, which provides frequency response. The third station, Eagle Valley, is a newly constructed 671 MW CCGT natural gas plant. IPL took operational control and commenced commercial operations of this CCGT plant in April 2018. The fourth station, Georgetown, is a small peaking station that uses natural gas to power combustion turbines. As of December 31, 2018, IPL’s net electric generation capacity for winter is 3,667 MW and net summer capacity is 3,552 MW. IPALCO’s other direct subsidiary is Mid-America. Mid-America is the holding company for IPALCO’s unregulated activities, which have not been material to the financial statements in the periods covered by this report. IPALCO’s regulated business is conducted through IPL. IPALCO has two business segments: utility and nonutility. The utility segment consists of the operations of IPL and everything else is included in the nonutility segment. Principles of Consolidation IPALCO’s consolidated financial statements are prepared in accordance with GAAP and in conjunction with the rules and regulations of the SEC. The consolidated financial statements include the accounts of IPALCO, its regulated utility subsidiary, IPL, and its unregulated subsidiary, Mid-America. All intercompany items have been eliminated in consolidation. Certain costs for shared resources amongst IPL and IPALCO, such as labor and benefits, are allocated to each entity based on allocation methodologies that management believes to be reasonable. We have evaluated subsequent events through the date this report is issued. Financial Statement Presentation During 2018, we adopted a change in presentation on our Consolidated Balance Sheets and Consolidated Statements of Operations from a utility format to a traditional format. These changes combined or revised the order of certain balance sheet and income statement line items and resulted in the movement of certain immaterial balances within the Consolidated Statements of Operations and Consolidated Balance Sheets, but did not result in any material changes to the classification of any such amounts or have any impact on net assets or net income. Certain amounts from prior periods have been reclassified to conform to the current period presentation. 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 management is required to make. Actual results may differ from those estimates. Regulatory Accounting The retail utility operations of IPL are subject to the jurisdiction of the IURC. IPL’s wholesale power transactions are subject to the jurisdiction of the FERC. These agencies regulate IPL’s utility business operations, tariffs, accounting, depreciation allowances, services, issuances of securities and the sale and acquisition of utility properties. The financial statements of IPL are based on GAAP, including the provisions of FASB ASC 980 “Regulated Operations,” which gives recognition to the ratemaking and accounting practices of these agencies. See also Note 5, “Regulatory Assets and Liabilities” for a discussion of specific regulatory assets and liabilities. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents. Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral. The following table provides a summary of cash, cash equivalents and restricted cash amounts as shown on the Consolidated Statements of Cash Flows: As of December 31, 2018 2017 (In Thousands) Cash, cash equivalents and restricted cash Cash and cash equivalents $ 33,199 $ 30,681 Restricted cash 400 — Total cash, cash equivalents and restricted cash $ 33,599 $ 30,681 Revenues and Accounts Receivable Revenues related to the sale of energy are generally recognized when service is rendered or energy is delivered to customers. However, the determination of the energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to certain customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making its estimates of unbilled revenue, IPL uses complex models that consider various factors including daily generation volumes; known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in future periods when revenue is billed. An allowance for potential credit losses is maintained and amounts are written off when normal collection efforts have been exhausted. Our provision for doubtful accounts included in “Operating expenses - Operation and maintenance” on the accompanying Consolidated Statements of Operations was $6.0 million , $5.9 million and $ 4.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. IPL’s basic rates include a provision for fuel costs as established in IPL’s most recent rate proceeding, which last adjusted IPL’s rates in December 2018. IPL is permitted to recover actual costs of purchased power and fuel consumed, subject to certain restrictions. This is accomplished through quarterly FAC proceedings, in which IPL estimates the amount of fuel and purchased power costs in future periods. Through these proceedings, IPL is also permitted to recover, in future rates, underestimated fuel and purchased power costs from prior periods, subject to certain restrictions, and therefore the over or underestimated costs are deferred or accrued and amortized into fuel expense in the same period that IPL’s rates are adjusted. See also Note 2, “ Regulatory Matters ” for a discussion of other costs that IPL is permitted to recover through periodic rate adjustment proceedings and the status of current rate adjustment proceedings. In addition, we are one of many transmission system owner members of MISO, a regional transmission organization which maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. See Note 13, " Revenue " for additional information of MISO sales and other revenue streams. The following table summarizes our accounts receivable balances at December 31: As of December 31, 2018 2017 (In Thousands) Accounts receivable, net Customer receivables $ 91,426 $ 94,168 Unbilled revenue 68,893 61,599 Amounts due from related parties 5,720 37 Other 4,341 4,640 Provision for uncollectible accounts (2,821 ) (2,830 ) Total accounts receivable, net $ 167,559 $ 157,614 Inventories We maintain coal, fuel oil, materials and supplies inventories for use in the production of electricity. These inventories are accounted for at the lower of cost or net realizable value, using the average cost. The following table summarizes our inventories balances at December 31: As of December 31, 2018 2017 (In Thousands) Inventories Fuel $ 32,457 $ 32,393 Materials and supplies 67,211 63,623 Total inventories $ 99,668 $ 96,016 Utility Plant and Depreciation Utility plant is stated at original cost as defined for regulatory purposes. The cost of additions to utility plant and replacements of retirement units of property are charged to plant accounts. Units of property replaced or abandoned in the ordinary course of business are retired from the plant accounts at cost; such amounts, less salvage, are charged to accumulated depreciation. Depreciation is computed by the straight-line method based on functional rates approved by the IURC and averaged 4.2% , 4.1% , and 4.3% during 2018 , 2017 and 2016 , respectively. Depreciation expense was $235.2 million , $209.8 million , and $209.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. "Depreciation and amortization" expense on the accompanying Consolidated Statements of Operations is presented net of regulatory deferrals of depreciation expense and also includes amortization of intangible assets and amortization of previously deferred regulatory costs. Allowance For Funds Used During Construction In accordance with the Uniform System of Accounts prescribed by FERC, IPL capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. For the Eagle Valley CCGT, Harding Street refueling projects, and NPDES projects, IPL capitalized amounts using a pretax composite rate of 6.4% , 6.6% and 7.1% during 2018 , 2017 and 2016 , respectively. For all other construction projects, IPL capitalized amounts using pretax composite rates of 6.4% , 6.6% and 7.2% during 2018 , 2017 and 2016 , respectively. Impairment of Long-lived Assets GAAP requires that we measure long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our utility plant assets was $4.1 billion and $4.0 billion as of December 31, 2018 and 2017 , respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and generating and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; the anticipated demand and relative pricing of retail electricity in our service territory and wholesale electricity in the region; and the cost of fuel. Intangible Assets Intangible assets primarily include capitalized software of $129.7 million and $99.4 million and its corresponding accumulated amortization of $88.8 million and $83.4 million , as of December 31, 2018 and 2017 , respectively. Amortization expense was $5.5 million , $4.3 million and $5.9 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The estimated amortization expense of this capitalized software is $30.2 million over the next 5 years ( $5.7 million in 2019, $6.9 million in 2020, $6.9 million in 2021, $6.9 million in 2022 and $3.8 million in 2023). Contingencies IPALCO accrues for loss contingencies when the amount of the loss is probable and estimable. IPL is subject to various environmental regulations, and is involved in certain legal proceedings. If IPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. As of December 31, 2018 and 2017 , total loss contingencies accrued were $4.6 million and $4.1 million , respectively, which were included in “Accrued and Other Current Liabilities” on the accompanying Consolidated Balance Sheets. Concentrations of Risk Substantially all of IPL’s customers are located within the Indianapolis area. Approximately 68% of IPL’s full-time employees are covered by collective bargaining agreements in two bargaining units: a physical unit and a clerical-technical unit. IPL’s contract with the physical unit expires on December 6, 2021 , and the contract with the clerical-technical unit expires February 17, 2020 . Additionally, IPL has long-term coal contracts with four suppliers, with about 46% of our existing coal under contract for the three-year period ending December 31, 2021 coming from one supplier. Substantially all of the coal is currently mined in the state of Indiana. Derivatives We have only limited involvement with derivative financial instruments and do not use them for trading purposes. IPALCO accounts for its derivatives in accordance with ASC 815 “Derivatives and Hedging.” In addition, IPL has entered into contracts involving the physical delivery of energy and fuel. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, IPL has elected to account for them as accrual contracts, which are not adjusted for changes in fair value. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, and their respective income tax bases. The Company establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company’s tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. The Company’s policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations. Income tax assets or liabilities which are includable in allowable costs for ratemaking purposes in future years are recorded as regulatory assets or liabilities with a corresponding deferred tax liability. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. Pension and Postretirement Benefits We recognize in our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes in the funded status, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans. We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans. Repair and Maintenance Costs Repair and maintenance costs are expensed as incurred. Per Share Data IPALCO is owned by AES U.S. Investments and CDPQ. IPALCO does not report earnings on a per-share basis. New Accounting Pronouncements Adopted in 2018 The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2018-15, Intangibles— Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This standard aligns the accounting for implementation costs incurred for a cloud computing arrangement that is a service with the requirement for capitalizing implementation costs associated with developing or obtaining internal-use software. Transition method: retrospective or prospective. October 1, 2018 The Company elected to early-adopt this standard on a prospective basis, effective for fiscal year 2018. The adoption of this standard did not have a material impact on the financial statements. 2018-14, Compensation— Retirement Benefits— Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework This standard modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Transition method: retrospective. Early adoption elected, January 1, 2018. Impact limited to changes in financial statement disclosures. 2017-07, Compensation— This standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization. Transition method: retrospective for presentation of non-service cost expense and prospective for the change in capitalization. January 1, 2018 The adoption of this standard resulted in a $(2.0) million and $1.0 million reclassification of non-service pension costs (credits) from Operating Expenses - Operations and maintenance to Other income/(expense), net for 2017 and 2016, respectively. 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 No material impact upon adoption of the standard. 2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606) See discussion of the ASUs below. January 1, 2018 See impact upon adoption of the standard below. Adoption of ASC Topic 606, “ Revenue from Contracts with Customers ” On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers”, and its subsequent corresponding updates (“ASC 606”). Under this standard, 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 services. The Company applied the modified retrospective method of adoption to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, the Company reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. There was no cumulative effect to our January 1, 2018 Consolidated Balance Sheet resulting from the adoption of ASC 606. New Accounting Pronouncements Issued But Not Yet Effective The following table provides a brief description of recent accounting pronouncements that could have a material impact on the Company’s consolidated financial statements once adopted. 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 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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The standard updates the hedge accounting model to expand the ability to hedge nonfinancial and financial risk components, reduce complexity, and ease certain documentation and assessment requirements. When facts and circumstances are the same as at the previous quantitative test, a subsequent quantitative effectiveness test is not required. The standard also eliminates the requirement to separately measure and report hedge ineffectiveness. For cash flow hedges, this means that the entire change in the fair value of a hedging instrument will be recorded in other comprehensive income and amounts deferred will be reclassified to earnings in the same income statement line as the hedged item. Transition method: modified retrospective with the cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date. Prospective for presentation and disclosures. January 1, 2019. Early adoption is permitted. The Company is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2018-19, 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. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses as it is done today, except that the losses will be recognized as an allowance rather than a reduction in the amortized cost of the securities. 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, 2018-01, 2018-10, 2018-11, 2018-20, Leases (Topic 842) See discussion of the ASUs below. January 1, 2019. Early adoption is permitted. The Company adopted the standard on January 1, 2019; see below for the evaluation of the impact of its adoption on its consolidated financial statements. ASU 2016-02 and its subsequent corresponding updates require lessees to recognize assets and liabilities for most leases, and recognize expenses in a manner similar to the current accounting method. For lessors, the guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. The guidance also eliminates current real estate-specific provisions. The standard must be adopted using a modified retrospective approach. The FASB has provided an optional transition method, which the Company has elected, that allows entities to continue to apply the guidance in ASC 840 Leases to the comparative periods presented in the year of adoption. Under this transition method, the Company will apply the transition provisions starting on January 1, 2019. The Company has elected to apply a package of practical expedients that allow lessees and lessors not to reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842. These three practical expedients must be elected as a package and must be consistently applied to all leases. The Company has also elected to apply an optional transition practical expedient for land easements that allows an entity to continue applying its current accounting policy for all land easements that exist before the standard's effective date that were not previously accounted for under ASC 840. The Company established a task force focused on the identification of contracts that are under the scope of the new standard and the assessment and measurement of their corresponding right-of-use assets and related liabilities. Additionally, the implementation team has been working on the configuration of a lease accounting tool that will support the implementation and the subsequent accounting. The implementation team has also evaluated changes to our business processes, systems and controls to support recognition and disclosure under the new standard. Under ASC 842, it is expected that fewer contracts will contain a lease. However, due to the elimination of today's real estate-specific guidance and changes to certain lessor classification criteria, more leases will qualify as sales-type leases and direct financing leases. Under these two models, a lessor will derecognize the asset and will recognize a lease receivable. According to ASC 842, the lease receivable includes the fair value of the plant after the contract period but does not include any variable payment such as margin on the sale of energy. Therefore, the lease receivable could be significantly different than the carrying amount of the underlying asset at lease commencement. In such circumstances, the difference between the initially recognized lease receivable and the carrying amount of the underlying asset is recognized as a gain/loss at lease commencement. The adoption of ASC 842 did not have a material impact on our consolidated financial statements. |

Overview and Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES IPL was incorporated under the laws of the state of Indiana in 1926. All of the outstanding common stock of IPL is owned by IPALCO. IPALCO, acquired by AES in March 2001, is owned by AES U.S. Investments and CDPQ. AES U.S. Investments is owned by AES ( 85% ) and CDPQ ( 15% ). IPL is engaged primarily in generating, transmitting, distributing and selling of electric energy to more than 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. Our largest generating station, Petersburg, is coal-fired. The second largest station, Harding Street, uses natural gas and fuel oil to power combustion turbines. In addition, IPL operates a 20 MW battery energy storage unit at this location, which provides frequency response. The third station, Eagle Valley, is a newly constructed 671 MW CCGT natural gas plant. IPL took operational control and commenced commercial operations of this CCGT plant in April 2018. The fourth station, Georgetown, is a small peaking station that uses natural gas to power combustion turbines. As of December 31, 2018, IPL’s net electric generation capacity for winter is 3,667 MW and net summer capacity is 3,552 MW. Principles of Consolidation IPL’s consolidated financial statements are prepared in accordance with GAAP and in conjunction with the rules and regulations of the SEC. The consolidated financial statements include the accounts of IPL and its unregulated subsidiary, IPL Funding Corporation, which was dissolved in 2018 and was immaterial to the consolidated financial statements in the periods covered by this report. All intercompany items have been eliminated in consolidation. Certain costs for shared resources amongst IPL and IPALCO, such as labor and benefits, are allocated to each entity based on allocation methodologies that management believes to be reasonable. We have evaluated subsequent events through the date this report is issued. Financial Statement Presentation During 2018, IPL adopted a change in presentation on its Consolidated Balance Sheets and Consolidated Statements of Operations from a utility format to a traditional format. These changes revised the order of certain balance sheet line items and resulted in the movement of certain balances within the Consolidated Statements of Operations and Consolidated Balance Sheets, but did not result in any material changes to the classification of any such amounts between line items or have any impact on net assets or net income. Certain amounts from prior periods have been reclassified to conform to the current period presentation. 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 management is required to make. Actual results may differ from those estimates. Regulatory Accounting The retail utility operations of IPL are subject to the jurisdiction of the IURC. IPL’s wholesale power transactions are subject to the jurisdiction of the FERC. These agencies regulate IPL’s utility business operations, tariffs, accounting, depreciation allowances, services, issuances of securities and the sale and acquisition of utility properties. The financial statements of IPL are based on GAAP, including the provisions of FASB ASC 980 “Regulated Operations,” which gives recognition to the ratemaking and accounting practices of these agencies. See also Note 5, “Regulatory Assets and Liabilities” for a discussion of specific regulatory assets and liabilities. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents. Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral. The following table provides a summary of cash, cash equivalents and restricted cash amounts as shown on the Consolidated Statements of Cash Flows: As of December 31, 2018 2017 (In Thousands) Cash, cash equivalents and restricted cash Cash and cash equivalents $ 26,834 $ 12,342 Restricted cash 400 — Total cash, cash equivalents and restricted cash $ 27,234 $ 12,342 Revenues and Accounts Receivable Revenues related to the sale of energy are generally recognized when service is rendered or energy is delivered to customers. However, the determination of the energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to certain customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making its estimates of unbilled revenue, IPL uses complex models that consider various factors including daily generation volumes; known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in future periods when revenue is billed. An allowance for potential credit losses is maintained and amounts are written off when normal collection efforts have been exhausted. IPL’s provision for doubtful accounts included in “ Operating expenses - Operation and maintenance” on the accompanying Consolidated Statements of Operations was $6.0 million , $5.9 million and $4.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. IPL’s basic rates include a provision for fuel costs as established in IPL’s most recent rate proceeding, which last adjusted IPL’s rates in December 2018. IPL is permitted to recover actual costs of purchased power and fuel consumed, subject to certain restrictions. This is accomplished through quarterly FAC proceedings, in which IPL estimates the amount of fuel and purchased power costs in future periods. Through these proceedings, IPL is also permitted to recover, in future rates, underestimated fuel and purchased power costs from prior periods, subject to certain restrictions, and therefore the over or underestimated costs are deferred or accrued and amortized into fuel expense in the same period that IPL’s rates are adjusted. See also Note 2, “ Regulatory Matters ” for a discussion of other costs that IPL is permitted to recover through periodic rate adjustment proceedings and the status of current rate adjustment proceedings. In addition, IPL is one of many transmission system owner members of MISO, a regional transmission organization which maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. See Note 13, " Revenue " for additional information of MISO sales and other revenue streams. The following table summarizes our accounts receivable balances at December 31: As of December 31, 2018 2017 (In Thousands) Accounts receivable, net Customer receivables $ 91,426 $ 94,168 Unbilled revenue 68,893 61,599 Amounts due from related parties 6,030 125 Other 4,341 4,640 Provision for uncollectible accounts (2,821 ) (2,830 ) Total accounts receivable, net $ 167,869 $ 157,702 Inventories IPL maintains coal, fuel oil, materials and supplies inventories for use in the production of electricity. These inventories are accounted for at the lower of cost or net realizable value, using the average cost. The following table summarizes our inventories balances at December 31: As of December 31, 2018 2017 (In Thousands) Inventories Fuel $ 32,457 $ 32,393 Materials and supplies 67,212 63,624 Total inventories $ 99,669 $ 96,017 Utility Plant and Depreciation Utility plant is stated at original cost as defined for regulatory purposes. The cost of additions to utility plant and replacements of retirement units of property are charged to plant accounts. Units of property replaced or abandoned in the ordinary course of business are retired from the plant accounts at cost; such amounts, less salvage, are charged to accumulated depreciation. Depreciation is computed by the straight-line method based on functional rates approved by the IURC and averaged 4.2% , 4.1% , and 4.3% during 2018 , 2017 and 2016 , respectively. Depreciation expense was $235.2 million , $209.8 million , and $209.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. "Depreciation and amortization" expense on the accompanying Consolidated Statements of Operations is presented net of regulatory deferrals of depreciation expense and also includes amortization of intangible assets and amortization of previously deferred regulatory costs. Allowance For Funds Used During Construction In accordance with the Uniform System of Accounts prescribed by FERC, IPL capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. For the Eagle Valley CCGT, Harding Street refueling projects, and NPDES projects, IPL capitalized amounts using a pretax composite rate of 6.4% , 6.6% and 7.1% during 2018 , 2017 and 2016 , respectively. For all other construction projects, IPL capitalized amounts using pretax composite rates of 6.4% , 6.6% and 7.2% during 2018 , 2017 and 2016 , respectively. Impairment of Long-lived Assets GAAP requires that IPL measures long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, IPL is required to write down the asset to its fair value with a charge to current earnings. The net book value of IPL’s utility plant assets was $4.1 billion and $4.0 billion as of December 31, 2018 and 2017 , respectively. IPL does not believe any of these assets are currently impaired. In making this assessment, IPL considers such factors as: the overall condition and generating and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; the anticipated demand and relative pricing of retail electricity in its service territory and wholesale electricity in the region; and the cost of fuel. Intangible Assets Intangible assets primarily include capitalized software of $129.7 million and $99.4 million and its corresponding accumulated amortization of $88.8 million and $83.4 million , as of December 31, 2018 and 2017 , respectively. Amortization expense was $5.5 million , $4.3 million and $5.9 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The estimated amortization expense of this capitalized software is $30.2 million over the next 5 years ( $5.7 million in 2019, $6.9 million in 2020, $6.9 million in 2021, $6.9 million in 2022 and $3.8 million in 2023). Contingencies IPL accrues for loss contingencies when the amount of the loss is probable and estimable. IPL is subject to various environmental regulations, and is involved in certain legal proceedings. If IPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. As of December 31, 2018 and 2017 , total loss contingencies accrued were $4.6 million and $4.1 million , respectively, which were included in “ Accrued and Other Current Liabilities” on the accompanying Consolidated Balance Sheets. Concentrations of Risk Substantially all of IPL’s customers are located within the Indianapolis area. Approximately 68% of IPL’s full-time employees are covered by collective bargaining agreements in two bargaining units: a physical unit and a clerical-technical unit. IPL’s contract with the physical unit expires on December 6, 2021 , and the contract with the clerical-technical unit expires February 17, 2020 . Additionally, IPL has long-term coal contracts with four suppliers, with about 46% of our existing coal under contract for the three-year period ending December 31, 2021 coming from one supplier. Substantially all of the coal is currently mined in the state of Indiana. Derivatives IPL has only limited involvement with derivative financial instruments and do not use them for trading purposes. IPL accounts for its derivatives in accordance with ASC 815 “Derivatives and Hedging.” In addition, IPL has entered into contracts involving the physical delivery of energy and fuel. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, IPL has elected to account for them as accrual contracts, which are not adjusted for changes in fair value. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, and their respective income tax bases. IPL establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. IPL’s tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. IPL’s policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations. Income tax assets or liabilities which are includable in allowable costs for ratemaking purposes in future years are recorded as regulatory assets or liabilities with a corresponding deferred tax liability. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. Pension and Postretirement Benefits IPL recognizes in its Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes in the funded status, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. All plan assets are recorded at fair value. IPL follows the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans. IPL accounts for and discloses pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715, IPL applies a disaggregated discount rate approach for determining service cost and interest cost for its defined benefit pension plans and postretirement plans. Repair and Maintenance Costs Repair and maintenance costs are expensed as incurred. Per Share Data IPALCO owns all of the outstanding common stock of IPL. IPL does not report earnings on a per-share basis. New Accounting Pronouncements Adopted in 2018 The following table provides a brief description of recent accounting pronouncements that had an impact on IPL's consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or did not have a material impact on IPL's consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2018-15, Intangibles— Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This standard aligns the accounting for implementation costs incurred for a cloud computing arrangement that is a service with the requirement for capitalizing implementation costs associated with developing or obtaining internal-use software. Transition method: retrospective or prospective. October 1, 2018 IPL elected to early-adopt this standard on a prospective basis, effective for fiscal year 2018. The adoption of this standard did not have a material impact on the financial statements. 2018-14, Compensation— Retirement Benefits— Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework This standard modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Transition method: retrospective. Early adoption elected, January 1, 2018. Impact limited to changes in financial statement disclosures. 2017-07, Compensation— This standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization. Transition method: retrospective for presentation of non-service cost expense and prospective for the change in capitalization. January 1, 2018 The adoption of this standard resulted in a $(2.0) million and $1.0 million reclassification of non-service pension costs (credits) from Operating Expenses - Operations and maintenance to Other income/(expense), net for 2017 and 2016, respectively. 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 No material impact upon adoption of the standard. 2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606) See discussion of the ASUs below. January 1, 2018 See impact upon adoption of the standard below. Adoption of ASC Topic 606, “ Revenue from Contracts with Customers ” On January 1, 2018, IPL adopted ASU 2014-09, “Revenue from Contracts with Customers”, and its subsequent corresponding updates (“ASC 606”). Under this standard, 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 services. IPL applied the modified retrospective method of adoption to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, IPL reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. There was no cumulative effect to IPL's January 1, 2018 Consolidated Balance Sheet resulting from the adoption of ASC 606. New Accounting Pronouncements Issued But Not Yet Effective The following table provides a brief description of recent accounting pronouncements that could have a material impact on IPL's consolidated financial statements once adopted. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on IPL's 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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The standard updates the hedge accounting model to expand the ability to hedge nonfinancial and financial risk components, reduce complexity, and ease certain documentation and assessment requirements. When facts and circumstances are the same as at the previous quantitative test, a subsequent quantitative effectiveness test is not required. The standard also eliminates the requirement to separately measure and report hedge ineffectiveness. For cash flow hedges, this means that the entire change in the fair value of a hedging instrument will be recorded in other comprehensive income and amounts deferred will be reclassified to earnings in the same income statement line as the hedged item. Transition method: modified retrospective with the cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date. Prospective for presentation and disclosures. January 1, 2019. Early adoption is permitted. IPL is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2018-19, 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. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses as it is done today, except that the losses will be recognized as an allowance rather than a reduction in the amortized cost of the securities. Transition method: various. January 1, 2020 Early adoption is permitted only as of January 1, 2019. IPL is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-02, 2018-01, 2018-10, 2018-11, 2018-20, Leases (Topic 842) See discussion of the ASUs below. January 1, 2019. Early adoption is permitted. IPL adopted the standard on January 1, 2019; see below for the evaluation of the impact of its adoption on its consolidated financial statements. ASU 2016-02 and its subsequent corresponding updates require lessees to recognize assets and liabilities for most leases, and recognize expenses in a manner similar to the current accounting method. For lessors, the guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. The guidance also eliminates current real estate-specific provisions. The standard must be adopted using a modified retrospective approach. The FASB has provided an optional transition method, which IPL has elected, that allows entities to continue to apply the guidance in ASC 840 Leases to the comparative periods presented in the year of adoption. Under this transition method, IPL will apply the transition provisions starting on January 1, 2019. IPL has elected to apply a package of practical expedients that allow lessees and lessors not to reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842. These three practical expedients must be elected as a package and must be consistently applied to all leases. IPL has also elected to apply an optional transition practical expedient for land easements that allows an entity to continue applying its current accounting policy for all land easements that exist before the standard's effective date that were not previously accounted for under ASC 840. IPL established a task force focused on the identification of contracts that are under the scope of the new standard and the assessment and measurement of their corresponding right-of-use assets and related liabilities. Additionally, the implementation team has been working on the configuration of a lease accounting tool that will support the implementation and the subsequent accounting. The implementation team has also evaluated changes to our business processes, systems and controls to support recognition and disclosure under the new standard. Under ASC 842, it is expected that fewer contracts will contain a lease. However, due to the elimination of today's real estate-specific guidance and changes to certain lessor classification criteria, more leases will qualify as sales-type leases and direct financing leases. Under these two models, a lessor will derecognize the asset and will recognize a lease receivable. According to ASC 842, the lease receivable includes the fair value of the plant after the contract period but does not include any variable payment such as margin on the sale of energy. Therefore, the lease receivable could be significantly different than the carrying amount of the underlying asset at lease commencement. In such circumstances, the difference between the initially recognized lease receivable and the carrying amount of the underlying asset is recognized as a gain/loss at lease commencement. The adoption of ASC 842 did not have a material impact on IPL's consolidated financial statements. |

Regulatory Matters | REGULATORY MATTERS General IPL is subject to regulation by the IURC as to its services and facilities, the valuation of property, the construction, purchase, or lease of electric generating facilities, the classification of accounts, rates of depreciation, retail rates and charges, the issuance of securities (other than evidences of indebtedness payable less than twelve months after the date of issue), the acquisition and sale of some public utility properties or securities and certain other matters. In addition, IPL is subject to the jurisdiction of the FERC with respect to, among other things, short-term borrowings not regulated by the IURC, the sale of electricity at wholesale, the transmission of electric energy in interstate commerce, the classification of accounts, reliability standards, and the acquisition and sale of utility property in certain circumstances as provided by the Federal Power Act. As a regulated entity, IPL is required to use certain accounting methods prescribed by regulatory bodies which may differ from those accounting methods required to be used by unregulated entities. IPL is also affected by the regulatory jurisdiction of the EPA at the federal level, and the IDEM at the state level. Other significant regulatory agencies affecting IPL include, but are not limited to, the NERC, the U.S. Department of Labor and the IOSHA. Basic Rates and Charges Our basic rates and charges represent the largest component of our annual revenues. Our basic rates and charges are determined after giving consideration, on a pro-forma basis, to all allowable costs for ratemaking purposes including a fair return on the fair value of the utility property used and useful in providing service to customers. These basic rates and charges are set and approved by the IURC after public hearings. Such proceedings, which have occurred at irregular intervals, involve IPL, the IURC, the Indiana Office of Utility Consumer Counselor, and other interested stakeholders. Pursuant to statute, the IURC is to conduct a periodic review of the basic rates and charges of all Indiana utilities at least once every four years, but the IURC has the authority to review the rates of any Indiana utility at any time. Once set, the basic rates and charges authorized do not assure the realization of a fair return on the fair value of property. Our declining block rate structure generally provides for residential and commercial customers to be charged a lower per kWh rate at higher consumption levels. Therefore, as volumes increase, the weighted average price per kWh decreases. Numerous factors including, but not limited to, weather, inflation, customer growth and usage, the level of actual operating and maintenance expenditures, capital expenditures including those required by environmental regulations, fuel costs, and generating unit availability, can affect the return realized. Base Rate Orders On October 31, 2018, the IURC issued an order approving an uncontested settlement agreement previously filed with the IURC by IPL for a $43.9 million , or 3.2% , increase to annual revenues (the "2018 Base Rate Order"). The 2018 Base Rate Order includes recovery through rates of the CCGT at Eagle Valley completed in the first half of 2018, as well as other construction projects and changes to operating income since the 2016 Base Rate Order (See below). New basic rates and charges became effective on December 5, 2018. The 2018 Base Rate Order also provides customers approximately $50 million in benefits, to be flowed to customers over a two-year period via the ECCRA rate adjustment mechanism beginning in March 2019. This liability is recorded in " Regulatory liabilities, non-current " as of December 31, 2018 on the accompanying Consolidated Balance Sheets. In addition, the 2018 Base Rate Order provides that annual wholesale margins earned above (or below) the benchmark of $16.3 million shall be passed back (or charged) to customers through a rate adjustment mechanism. Similarly, the 2018 Base Rate Order provides that all capacity sales above (or below) a benchmark of $11.3 million shall be passed back (or charged) to customers through a rate adjustment mechanism. The 2018 Base Rate Order also approved changes to IPL's depreciation and amortization rates (including no longer deferring depreciation on the CCGT at Eagle Valley) which altogether represent a net increase of approximately $28.7 million annually. In March 2016, the IURC issued the 2016 Base 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 are amortized to expense over ten years. 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 benchmark of $6.3 million . 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 was approximately $47 million . IPL’s bottom ash dewatering system at its Petersburg generating station went into service in September 2017. NAAQS On April 26, 2017, the IURC approved IPL’s request for NAAQS SO 2 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 SO 2 compliance plan was approximately $29 million . This project is expected to be fully in service in the first quarter of 2019. Other The DOE issued a Notice of Proposed Rule Making on September 29, 2017, which directed the FERC to exercise its authority to set just and reasonable rates that recognize the “ resiliency ” value provided by generation plants with certain characteristics, including having 90-days or more of on-site fuel and operating in markets where they do not receive rate base treatment through state ratemaking. Nuclear and coal-fired generation plants would have been most likely to be able to meet the requirements. As proposed, the DOE would value resiliency through rates that recover “ compensable costs ” that were defined to include the recovery of operating and fuel expenses, debt service and a fair return on equity. On January 8, 2018, the FERC issued an order terminating this docket stating that it failed to satisfy the legal requirements of Section 206 of the Federal Power Act of 1935. The FERC initiated a new docket to take additional steps to explore resilience issues in RTOs/ISOs. The goal of this new proceeding is to: (1) develop a common understanding among the FERC, State Commissions, RTOs/ISOs, transmission owners, and others as to what resilience of the bulk power system means and requires; (2) understand how each RTO and ISO assesses resilience in its geographic footprint; and (3) use this information to evaluate whether additional action regarding resilience is appropriate at this time. It is not possible to predict the impact of this proceeding on our business, financial condition and results of operations. FAC and Authorized Annual Jurisdictional Net Operating Income IPL may apply to the IURC for a change in IPL’s fuel charge every three months to recover IPL’s estimated fuel costs, including the energy portion of purchased power costs, which may be above or below the levels included in IPL’s basic rates and charges. IPL must present evidence in each FAC proceeding that it has made every reasonable effort to acquire fuel and generate or purchase power or both so as to provide electricity to its retail customers at the lowest fuel cost reasonably possible. Independent of the IURC’s ability to review basic rates and charges, Indiana law requires electric utilities under the jurisdiction of the IURC to meet operating expense and income test requirements as a condition for approval of requested changes in the FAC. Additionally, customer refunds may result if a utility’s rolling twelve-month operating income, determined at quarterly measurement dates, exceeds a utility’s authorized annual jurisdictional net operating income and there are not sufficient applicable cumulative net operating income deficiencies against which the excess rolling twelve-month jurisdictional net operating income can be offset. ECCRA IPL may apply to the IURC for approval of a rate adjustment known as the ECCRA periodically to recover costs (including a return) to comply with certain environmental regulations applicable to IPL’s generating stations. The total amount of IPL’s equipment approved for ECCRA recovery as of December 31, 2018 was $12.1 million . The jurisdictional revenue requirement approved by the IURC to be included in IPL’s rates for the six-month period ending February 2019 was $16.2 million . This amount is significantly lower than prior ECCRA periods as a result of having the vast majority of the ECCRA projects rolled into IPL’s basic rates and charges effective December 5, 2018 as a result of the 2018 Base Rate Order. Further, the ECCRA jurisdictional revenue requirement starting March 2019 is expected to be a negative amount to reflect certain one-time credits IPL is required to pass through to its customers over a two-year period (totaling $50.2 million ) as a result of the 2018 Base Rate Order. The only equipment still remaining in the ECCRA as of December 31, 2018 are certain projects associated with NAAQS compliance. DSM Through various rate orders from the IURC, IPL has been able to recover its costs of implementing various DSM programs throughout the periods covered by this report. In 2016 and 2018, IPL also had the ability to receive performance incentives, dependent upon the level of success of the programs. Performance incentives included in revenues for the years ended December 31, 2018, 2017 and 2016 were $3.8 million , $0.0 million and $10.7 million , respectively. On February 7, 2018, the IURC approved a settlement agreement establishing a new three year DSM plan for IPL through 2020. The approval included cost recovery of programs as well as performance incentives, depending on the level of success of the programs. The order also approved recovery of lost revenues, consistent with the provisions of the settlement agreement. Wind and Solar Power Purchase Agreements We are committed under a power purchase agreement to purchase all wind-generated electricity through 2029 from a wind project in Indiana. We are also committed under another agreement to purchase all wind-generated electricity through 2031 from a project in Minnesota. The Indiana project has a maximum output capacity of approximately 100 MW and the Minnesota project has a maximum output capacity of approximately 200 MW. In addition, we have 96.4 MW of solar-generated electricity in our service territory under long-term contracts in 2019 (these long-term contracts have expiration dates ranging from 2021 to 2033), of which 95.9 MW was in operation as of December 31, 2018 . We have authority from the IURC to recover the costs for all of these agreements through an adjustment mechanism administered within the FAC. If and when IPL sells the renewable energy attributes (in the form of renewable energy credits) generated from these facilities, the proceeds are passed back to IPL’s retail customers through the FAC. Taxes On January 3, 2018, the IURC opened a generic investigation to review and consider the impacts from the TCJA and how any resulting benefits should be realized by customers. The IURC’s order opening this investigation directed Indiana utilities to apply regulatory accounting treatment, such as the use of regulatory assets and regulatory liabilities, for all estimated impacts resulting from the TCJA. On February 16, 2018, the IURC issued an order establishing two phases of the investigation. The first phase (“Phase I”) directed respondent utilities (including IPL) to make a filing to remove from respondents’ rates and charges for service, the impact of a lower federal income tax rate. The second phase (“Phase II”) was established to address remaining issues from the TCJA, including treatment of deferred taxes and how these benefits will be realized by customers. On August 29, 2018, the IURC approved a settlement agreement filed by IPL and various other parties to resolve the Phase I issues of the TCJA tax expense via a credit through the ECCRA rate adjustment mechanism of $9.5 million . The 2018 Base Rate Order described above resolved the Phase II and all other issues regarding the TCJA impact on IPL's rates and includes an additional credit of $14.3 million to be paid by IPL to its customers through the ECCRA rate adjustment mechanism over two years beginning in March 2019.

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 was approximately $47 million . IPL’s bottom ash dewatering system at its Petersburg generating station went into service in September 2017. NAAQS On April 26, 2017, the IURC approved IPL’s request for NAAQS SO 2 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 SO 2 compliance plan was approximately $29 million . This project is expected to be fully in service in the first quarter of 2019. Other The DOE issued a Notice of Proposed Rule Making on September 29, 2017, which directed the FERC to exercise its authority to set just and reasonable rates that recognize the “ resiliency ” value provided by generation plants with certain characteristics, including having 90-days or more of on-site fuel and operating in markets where they do not receive rate base treatment through state ratemaking. Nuclear and coal-fired generation plants would have been most likely to be able to meet the requirements. As proposed, the DOE would value resiliency through rates that recover “ compensable costs ” that were defined to include the recovery of operating and fuel expenses, debt service and a fair return on equity. On January 8, 2018, the FERC issued an order terminating this docket stating that it failed to satisfy the legal requirements of Section 206 of the Federal Power Act of 1935. The FERC initiated a new docket to take additional steps to explore resilience issues in RTOs/ISOs. The goal of this new proceeding is to: (1) develop a common understanding among the FERC, State Commissions, RTOs/ISOs, transmission owners, and others as to what resilience of the bulk power system means and requires; (2) understand how each RTO and ISO assesses resilience in its geographic footprint; and (3) use this information to evaluate whether additional action regarding resilience is appropriate at this time. It is not possible to predict the impact of this proceeding on our business, financial condition and results of operations. FAC and Authorized Annual Jurisdictional Net Operating Income IPL may apply to the IURC for a change in IPL’s fuel charge every three months to recover IPL’s estimated fuel costs, including the energy portion of purchased power costs, which may be above or below the levels included in IPL’s basic rates and charges. IPL must present evidence in each FAC proceeding that it has made every reasonable effort to acquire fuel and generate or purchase power or both so as to provide electricity to its retail customers at the lowest fuel cost reasonably possible. Independent of the IURC’s ability to review basic rates and charges, Indiana law requires electric utilities under the jurisdiction of the IURC to meet operating expense and income test requirements as a condition for approval of requested changes in the FAC. Additionally, customer refunds may result if a utility’s rolling twelve-month operating income, determined at quarterly measurement dates, exceeds a utility’s authorized annual jurisdictional net operating income and there are not sufficient applicable cumulative net operating income deficiencies against which the excess rolling twelve-month jurisdictional net operating income can be offset. ECCRA IPL may apply to the IURC for approval of a rate adjustment known as the ECCRA periodically to recover costs (including a return) to comply with certain environmental regulations applicable to IPL’s generating stations. The total amount of IPL’s equipment approved for ECCRA recovery as of December 31, 2018 was $12.1 million . The jurisdictional revenue requirement approved by the IURC to be included in IPL’s rates for the six-month period ending February 2019 was $16.2 million . This amount is significantly lower than prior ECCRA periods as a result of having the vast majority of the ECCRA projects rolled into IPL’s basic rates and charges effective December 5, 2018 as a result of the 2018 Base Rate Order. Further, the ECCRA jurisdictional revenue requirement starting March 2019 is expected to be a negative amount to reflect certain one-time credits IPL is required to pass through to its customers over a two-year period (totaling $50.2 million ) as a result of the 2018 Base Rate Order. The only equipment still remaining in the ECCRA as of December 31, 2018 are certain projects associated with NAAQS compliance. DSM Through various rate orders from the IURC, IPL has been able to recover its costs of implementing various DSM programs throughout the periods covered by this report. In 2016 and 2018, IPL also had the ability to receive performance incentives, dependent upon the level of success of the programs. Performance incentives included in revenues for the years ended December 31, 2018, 2017 and 2016 were $3.8 million , $0.0 million and $10.7 million , respectively. On February 7, 2018, the IURC approved a settlement agreement establishing a new three year DSM plan for IPL through 2020. The approval included cost recovery of programs as well as performance incentives, depending on the level of success of the programs. The order also approved recovery of lost revenues, consistent with the provisions of the settlement agreement. Wind and Solar Power Purchase Agreements IPL is committed under a power purchase agreement to purchase all wind-generated electricity through 2029 from a wind project in Indiana. IPL is also committed under another agreement to purchase all wind-generated electricity through 2031 from a project in Minnesota. The Indiana project has a maximum output capacity of approximately 100 MW and the Minnesota project has a maximum output capacity of approximately 200 MW. In addition, IPL has 96.4 MW of solar-generated electricity in its service territory under long-term contracts in 2019 (these long-term contracts have expiration dates ranging from 2021 to 2033), of which 95.9 MW was in operation as of December 31, 2018 . IPL has authority from the IURC to recover the costs for all of these agreements through an adjustment mechanism administered within the FAC. If and when IPL sells the renewable energy attributes (in the form of renewable energy credits) generated from these facilities, the proceeds are passed back to IPL’s retail customers through the FAC. Taxes On January 3, 2018, the IURC opened a generic investigation to review and consider the impacts from the TCJA and how any resulting benefits should be realized by customers. The IURC’s order opening this investigation directed Indiana utilities to apply regulatory accounting treatment, such as the use of regulatory assets and regulatory liabilities, for all estimated impacts resulting from the TCJA. On February 16, 2018, the IURC issued an order establishing two phases of the investigation. The first phase (“Phase I”) directed respondent utilities (including IPL) to make a filing to remove from respondents’ rates and charges for service, the impact of a lower federal income tax rate. The second phase (“Phase II”) was established to address remaining issues from the TCJA, including treatment of deferred taxes and how these benefits will be realized by customers. On August 29, 2018, the IURC approved a settlement agreement filed by IPL and various other parties to resolve the Phase I issues of the TCJA tax expense via a credit through the ECCRA rate adjustment mechanism of $9.5 million . The 2018 Base Rate Order described above resolved the Phase II and all other issues regarding the TCJA impact on IPL's rates and includes an additional credit of $14.3 million to be paid by IPL to its customers through the ECCRA rate adjustment mechanism over two years beginning in March 2019.

Entity Information [Line Items] | |
Fair Value | FAIR VALUE The fair value of financial assets and liabilities approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. As these amounts are estimates and based on hypothetical transactions to sell assets or transfer liabilities, the use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. Fair Value Hierarchy and Valuation Techniques 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. 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. VEBA Assets IPL has VEBA investments that are to be used to fund certain employee postretirement health care benefit plans. These assets are primarily comprised of open-ended mutual funds, which are valued using the net assets value per unit. These investments are recorded at fair value within " Other non-current assets " on the accompanying Consolidated Balance Sheets and classified as equity securities. ASU 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities” was effective as of January 1, 2018. This ASU requires the change in the fair value of equity instruments to be recorded in income. Equity Instruments were defined to include all mutual funds, regardless of the underlying investments. Therefore, all changes to fair value on the VEBA investments will be included in income in the period that the changes occur. These changes to fair value were not material for the years ended December 31, 2018, 2017, or 2016. Any unrealized gains or losses are recorded in our Consolidated Statements of Operations. FTRs In connection with IPL’s participation in MISO, in the second quarter of each year IPL is granted financial instruments that can be converted into cash or FTRs based on IPL’s forecasted peak load for the period. FTRs are used in the MISO market to hedge IPL’s exposure to congestion charges, which result from constraints on the transmission system. IPL converts all of these financial instruments into FTRs. IPL’s FTRs are valued at the cleared auction prices for FTRs in MISO’s annual auction. Because of the infrequent nature of this valuation, the fair value assigned to the FTRs is considered a Level 3 input under the fair value hierarchy required by ASC 820. An offsetting regulatory liability has been recorded as these revenues or costs will be flowed through to customers through the FAC. As such, there is no impact on our Consolidated Statements of Operations. Other Financial Liabilities As of December 31, 2018 and 2017 , IPALCO's other financial liabilities measured at fair value on a recurring basis were considered Level 3, based on the fair value hierarchy. Summary The fair value of assets and liabilities at December 31, 2018 measured on a recurring basis and the respective category within the fair value hierarchy for IPALCO was determined as follows: Assets and Liabilities at Fair Value Level 1 Level 2 Level 3 Fair value at December 31, 2018 Based on quoted market prices in active markets Other observable inputs Unobservable inputs (In Thousands) Financial assets: VEBA investments: Money market funds $ 21 $ 21 $ — $ — Mutual funds 2,565 — 2,565 — Total VEBA investments 2,586 21 2,565 — Financial transmission rights 3,099 — — 3,099 Total financial assets measured at fair value $ 5,685 $ 21 $ 2,565 $ 3,099 Financial liabilities: Other derivative liabilities $ 53 $ — $ — $ 53 Total financial liabilities measured at fair value $ 53 $ — $ — $ 53 The fair value of assets and liabilities at December 31, 2017 measured on a recurring basis and the respective category within the fair value hierarchy for IPALCO was determined as follows: Assets and Liabilities at Fair Value Level 1 Level 2 Level 3 Fair value at December 31, 2017 Based on quoted market prices in active markets Other observable inputs Unobservable inputs (In Thousands) Financial assets: VEBA investments: Money market funds $ 10 $ 10 $ — $ — Mutual funds 2,581 — 2,581 — Total VEBA investments 2,591 10 2,581 — Financial transmission rights 2,532 — — 2,532 Total financial assets measured at fair value $ 5,123 $ 10 $ 2,581 $ 2,532 Financial liabilities: Other derivative liabilities $ 78 $ — $ — $ 78 Total financial liabilities measured at fair value $ 78 $ — $ — $ 78 The following table sets forth a reconciliation of financial instruments, measured at fair value on a recurring basis, classified as Level 3 in the fair value hierarchy (note, amounts in this table indicate carrying values, which approximate fair values): Reconciliation of Financial Instruments Classified as Level 3 (In Thousands) Balance at January 1, 2017 $ 4,293 Unrealized gain recognized in earnings 23 Issuances 9,647 Settlements (11,509 ) Balance at December 31, 2017 $ 2,454 Unrealized gain recognized in earnings 24 Issuances 9,295 Settlements (8,727 ) Balance at December 31, 2018 $ 3,046 Non-Recurring Fair Value Measurements 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 using market based rates 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 inputs under the fair value hierarchy. In 2018, IPL recorded additional ARO liabilities of $54.8 million to reflect revisions to cash flow and timing estimates due to accelerated ash pond closure dates and revised estimated closure costs after review of updates to the CCR rule and revised estimated costs associated with IPL's coal storage areas. As of December 31, 2018 and 2017 , ARO liabilities were $129.5 million and $79.5 million , respectively. See Note 3, “Property, Plant and Equipment - ARO ” for a rollforward of the ARO liability. 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: December 31, 2018 December 31, 2017 Face Value Fair Value Face Value Fair Value (In Thousands) Fixed-rate $ 2,523,800 $ 2,649,265 $ 2,418,800 $ 2,655,012 Variable-rate 155,000 155,000 238,000 238,000 Total indebtedness $ 2,678,800 $ 2,804,265 $ 2,656,800 $ 2,893,012 The difference between the face value and the carrying value of this indebtedness represents the following: • unamortized deferred financing costs of $23.0 million and $24.4 million at December 31, 2018 and 2017 , respectively. • unamortized discounts of $6.7 million and $6.9 million at December 31, 2018 and 2017 , respectively. |

Regulatory Assets and Liabilities | REGULATORY ASSETS AND LIABILITIES Regulatory assets represent deferred costs or credits that have been included as allowable costs or credits for ratemaking purposes. IPL has recorded regulatory assets or liabilities relating to certain costs or credits as authorized by the IURC or established regulatory practices in accordance with ASC 980. IPL is amortizing non tax-related regulatory assets to expense over periods ranging from 1 to 28 years. Tax-related regulatory assets represent the net income tax costs to be considered in future regulatory proceedings generally as the tax-related amounts are paid. The amounts of regulatory assets and regulatory liabilities at December 31 are as follows: 2018 2017 Recovery Period (In Thousands) Regulatory Assets Current: Undercollections of rate riders $ 13,217 $ 22,990 Approximately 1 year (1) Costs being recovered through basic rates and charges 15,182 12,351 Approximately 1 year (1) Total current regulatory assets 28,399 35,341 Long-term: Unrecognized pension and other postretirement benefit plan costs 195,559 205,573 Various (2) Income taxes recoverable from customers 103 — Various Deferred MISO costs 88,052 101,562 Through 2026 (1) Unamortized Petersburg Unit 4 carrying charges and certain other costs 8,084 9,139 Through 2026 (1)(3) Unamortized reacquisition premium on debt 19,714 21,109 Over remaining life of debt Environmental projects 81,204 40,434 Through 2046 (1)(3) Other miscellaneous 2,361 1,087 Various (4) Total long-term regulatory assets 395,077 378,904 Total regulatory assets $ 423,476 $ 414,245 Regulatory Liabilities Current: Overcollections and other credits being passed to customers through rate riders $ 47,925 $ — Approximately 1 year (1) FTRs 3,099 2,532 Approximately 1 year (1) Total current regulatory liabilities 51,024 2,532 Long-term: ARO and accrued asset removal costs 707,662 696,973 Not applicable Income taxes payable to customers through rates 141,058 154,461 Various Long-term portion of credits being passed to customers through rate riders 21,341 — Through 2021 Other miscellaneous 194 320 To be determined Total long-term regulatory liabilities 870,255 851,754 Total regulatory liabilities $ 921,279 $ 854,286 (1) Recovered (credited) per specific rate orders (2) IPL receives a return on its discretionary funding (3) Recovered with a current return (4) The majority of these costs are being recovered in basic rates and charges through 2026. For the remainder, recovery is probable, but the timing is not yet determined. Deferred Fuel Deferred fuel costs are a component of current regulatory assets or liabilities (which is a result of IPL charging either more or less for fuel than our actual costs to our jurisdictional customers) and are expected to be recovered through future FAC proceedings. IPL records deferred fuel in accordance with standards prescribed by the FERC. The deferred fuel adjustment is the result of variances between estimated fuel and purchased power costs in IPL’s FAC and actual fuel and purchased power costs. IPL is generally permitted to recover underestimated fuel and purchased power costs in future rates through the FAC proceedings and therefore the costs are deferred when incurred and amortized into fuel expense in the same period that IPL’s rates are adjusted to reflect these costs. Unrecognized Pension and Postretirement Benefit Plan Costs In accordance with ASC 715 “Compensation – Retirement Benefits” and ASC 980, we recognize a regulatory asset equal to the unrecognized actuarial gains and losses and prior service costs. Pension expenses are recorded based on the benefit plan’s actuarially determined pension liability and associated level of annual expenses to be recognized. The other postretirement benefit plan’s deferred benefit cost is the excess of the other postretirement benefit liability over the amount previously recognized. Deferred Income Taxes Recoverable/Payable Through Rates A deferred income tax asset or liability is created from a difference in timing of income recognition between tax laws and accounting methods. As a regulated utility, IPL includes in ratemaking the impacts of current income taxes and changes in deferred income tax liabilities or assets. On December 22, 2017, the U.S. federal government enacted the TCJA, which, among other things, reduced the federal corporate income tax rate from 35% to 21% , beginning January 1, 2018. As required by GAAP, on December 31, 2017, IPL and IPALCO remeasured their deferred income tax assets and liabilities using the new tax rate. The impact of the reduction of the income tax rate on deferred income taxes was utilized in the 2018 Base Rate Order to reduce jurisdictional retail rates. Accordingly, we have a net regulatory deferred income tax liability of $141.1 million and $154.5 million as of December 31, 2018 and 2017 , respectively. Deferred MISO Costs These consist of administrative costs for transmission services, transmission expansion cost sharing, and certain other operational and administrative costs from the MISO market. These costs are being recovered per specific rate order. See Note 2, “Regulatory Matters.” Environmental Costs These consist of various costs incurred to comply with environmental regulations. These costs were approved for recovery either through IPL's ECCRA proceedings or in the 2018 Base Rate Order. Amortization periods vary, but all costs should be recovered by 2046. ARO and Accrued Asset Removal Costs In accordance with ASC 410 and ASC 980, IPL recognizes the amount collected in customer rates for costs of removal that do not have an associated legal retirement obligation as a deferred regulatory liability. This amount is net of the portion of legal ARO costs that is also currently being recovered in rates. |

Equity | EQUITY Paid In Capital and Capital Stock 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 this transaction, CDPQ’s direct (approximately 17.65% ) and indirect (approximately 12.35% ) interest in IPALCO was 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. Dividend Restrictions IPL’s mortgage and deed of trust and its amended articles of incorporation contain restrictions on IPL’s ability to issue certain securities or pay cash dividends. So long as any of the several series of bonds of IPL issued under its mortgage remains outstanding, and subject to certain exceptions, IPL is restricted in the declaration and payment of dividends, or other distribution on shares of its capital stock of any class, or in the purchase or redemption of such shares, to the aggregate of its net income, as defined in the mortgage, after December 31, 1939. In addition, pursuant to IPL’s articles, no dividends may be paid or accrued and no other distribution may be made on IPL’s common stock unless dividends on all outstanding shares of IPL preferred stock have been paid or declared and set apart for payment. As of December 31, 2018 and as of the filing of this report, IPL was in compliance with these restrictions. IPL is also restricted in its ability to pay dividends if it is in default under the terms of its Credit Agreement and its unsecured notes, which could happen if IPL fails to comply with certain covenants. These covenants, among other things, require IPL to maintain a ratio of total debt to total capitalization not in excess of 0.65 to 1 . As of December 31, 2018 and as of the filing of this report, IPL was in compliance with all covenants and no event of default existed. IPALCO is also restricted in its ability to pay dividends if it is in default under the terms of its Term Loan, which could happen if IPALCO fails to comply with certain covenants. These covenants, among other things, require IPALCO to maintain a ratio of total debt to total capitalization not in excess of 0.67 to 1 . As of December 31, 2018 and as of the filing of this report, IPALCO was in compliance with all covenants and no event of default existed. During the years ended December 31, 2018 , 2017 and 2016 , IPALCO paid dividends to its shareholders totaling $130.2 million , $105.1 million and $123.0 million , respectively. Cumulative Preferred Stock IPL has five separate series of cumulative preferred stock. Holders of preferred stock are entitled to receive dividends at rates per annum ranging from 4.0% to 5.65% . During each year ended December 31, 2018 , 2017 and 2016 , total preferred stock dividends declared were $3.2 million . Holders of preferred stock are entitled to two votes per share for IPL matters, and if four full quarterly dividends are in default on all shares of the preferred stock then outstanding, they are entitled to elect the smallest number of IPL directors to constitute a majority of IPL’s Board of Directors. Based on the preferred stockholders’ ability to elect a majority of IPL’s Board of Directors in this circumstance, the redemption of the preferred shares is considered to be not solely within the control of the issuer and the preferred stock was considered temporary equity and presented in the mezzanine level of the audited consolidated balance sheets in accordance with the relevant accounting guidance for non-controlling interests and redeemable securities. IPL has issued and outstanding 500,000 shares of 5.65% preferred stock, which are now redeemable at par value, subject to certain restrictions, in whole or in part. Additionally, IPL has 91,353 shares of preferred stock which are redeemable solely at the option of IPL and can be redeemed in whole or in part at any time at specific call prices.

Pursuant to the terms of the mortgage, substantially all property owned by IPL is subject to a first mortgage lien securing indebtedness of $1,713.8 million as of December 31, 2018 . The IPL first mortgage bonds require net earnings as calculated thereunder be at least two and one-half times the annual interest requirements before additional bonds can be authenticated on the basis of property additions. IPL was in compliance with such requirements as of December 31, 2018 . In May 2016, IPL issued $350 million aggregate principal amount of first mortgage bonds, 4.05% Series, due May 2046, pursuant to Rule 144A and Regulation S under the Securities Act. Net proceeds from this offering were approximately $343.6 million , after deducting the initial purchasers’ discounts and fees and expenses for the offering. The net proceeds from this offering were used to finance a portion of IPL’s construction program and capital costs related to environmental and replacement generation projects, to repay outstanding borrowings under IPL’s 364-day delayed-draw term loan and other short-term debt, and for other general corporate purposes. In December 2016, the Indiana Finance Authority issued on behalf of IPL an aggregate principal amount of $40.0 million of 3.125% Environmental Facilities Refunding Revenue Bonds, Series 2016A (Indianapolis Power & Light Company Project) due December 2024.

Net proceeds from this offering were approximately $103.5 million , after deducting the initial purchasers’ discounts and fees and expenses for the offering. The net proceeds from this offering were used to repay amounts due under IPL's Credit Agreement and for general corporate purposes. IPALCO Term Loan On October 31, 2018, IPALCO closed on a new Term Loan consisting of a $65 million credit facility maturing July 1, 2020. The Term Loan is variable rate and is secured by IPALCO’s pledge of all the outstanding common stock of IPL. The lien on the pledged shares is shared equally and ratably with IPALCO’ existing senior secured notes. The Term Loan proceeds were used to repay amounts under IPL's Credit Agreement and for general corporate purposes. IPALCO’s Senior Secured Notes In August 2017, IPALCO completed the sale of the $405 million 2024 IPALCO Notes pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended. The 2024 IPALCO Notes were issued pursuant to an Indenture dated August 22, 2017, by and between IPALCO and U.S. Bank, National Association, as trustee. The 2024 IPALCO Notes were priced to the public at 99.901% of the principal amount. Net proceeds to IPALCO were approximately $399.3 million after deducting underwriting costs and estimated offering expenses. These costs are being amortized to the maturity date using the effective interest method. We used the net proceeds from this offering, together with cash on hand, to redeem the $400 million 2018 IPALCO Notes on September 21, 2017, and to pay certain related fees, expenses and make-whole premiums. A loss on early extinguishment of debt of $8.9 million for the 2018 IPALCO Notes is included as a separate line item within “ Other Income/(Expense), Net ” in the accompanying Consolidated Statements of Operations. The 2020 IPALCO Notes and 2024 IPALCO Notes are secured by IPALCO’s pledge of all of the outstanding common stock of IPL. The lien on the pledged shares is shared equally and ratably with IPALCO’s Term Loan. IPALCO also agreed to register the 2024 IPALCO Notes under the Securities Act by filing an exchange offer registration statement or, under specified circumstances, a shelf registration statement with the SEC pursuant to a Registration Rights Agreement that IPALCO entered into with Morgan Stanley & Co. LLC and PNC Capital Markets LLC, as representatives of the initial purchasers of the 2024 IPALCO Notes, dated August 22, 2017.

This Credit Agreement is an unsecured committed line of credit to be used: (i) to finance capital expenditures; (ii) to support working capital; and (iii) for general corporate purposes. This agreement matures on October 16, 2020, and bears interest at variable rates as described in the Credit Agreement. It includes an uncommitted $150 million accordion feature to provide IPL with an option to request an increase in the size of the facility at any time prior to October 16, 2019, subject to approval by the lenders. Prior to execution, IPL and IPALCO had existing general banking relationships with the parties to the Credit Agreement. As of December 31, 2018 and 2017 , IPL had $0.0 million and $148.0 million in outstanding borrowings on the committed line of credit, respectively. Restrictions on Issuance of Debt 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. IPL has approval from FERC to borrow up to $500 million of short-term indebtedness outstanding at any time through July 26, 2020. In December 2018, IPL received an order from the IURC granting IPL authority through December 31, 2021 to, among other things, issue up to $350 million in aggregate principal amount of long-term debt and refinance up to $185.0 million in existing indebtedness, all of which authority remains available under the order as of December 31, 2018. This order also grants IPL authority to have up to $500 million of long-term credit agreements and liquidity facilities outstanding at any one time, of which $250.0 million remains available under the order as of December 31, 2018. 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 December 31, 2018. IPL also has 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. Under such restrictions, IPL is generally allowed to fully draw the amounts available on its Credit Agreement, refinance existing debt and issue new debt approved by the IURC and issue certain other indebtedness. 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 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. |

Income Taxes | INCOME TAXES IPALCO follows a policy of comprehensive interperiod income tax allocation. Investment tax credits related to utility property have been deferred and are being amortized over the estimated useful lives of the related property. AES files federal and state income tax returns which consolidate IPALCO and its subsidiaries. Under a tax sharing agreement with AES, IPALCO is responsible for the income taxes associated with its own taxable income and records the provision for income taxes as if IPALCO and its subsidiaries each filed separate income tax returns. IPALCO is no longer subject to U.S. or state income tax examinations for tax years through March 27, 2001, but is open for all subsequent periods. IPALCO made tax sharing payments to AES of $28.3 million , $65.1 million and $28.8 million in 2018, 2017 and 2016 respectively. On March 25, 2014, the state of Indiana amended Indiana Code 6-3-2-1 through Senate Bill 001, which phases in an additional 1.6% reduction to the state corporate income tax rate that was initially being reduced by 2% . While the statutory state income tax rate remained at 5.875% for the calendar year 2018, the deferred tax balances were adjusted according to the anticipated reversal of temporary differences. The change in required deferred taxes on plant and plant-related temporary differences resulted in a reduction to the associated regulatory asset of $1.3 million . The change in required deferred taxes on non-property related temporary differences which are not probable to cause a reduction in future base customer rates resulted in a tax benefit of $0.1 million . The statutory state corporate income tax rate will be 5.625% for 2019. In tax years prior to 2018, Internal Revenue Code Section 199 permitted taxpayers to claim a deduction from taxable income attributable to certain domestic production activities. IPL’s electric production activities qualify for this deduction. Beginning in 2010 and through the 2017 tax year, the deduction is equal to 9% of the taxable income attributable to qualifying production activity. The tax benefit associated with the Internal Revenue Code Section 199 domestic production deduction for the tax years 2017 and 2016 was $3.9 million and $2.9 million , respectively. Due to the recently enacted TCJA (as described below), the 2017 tax year was the final year for this deduction. U.S. Tax Reform On December 22, 2017, the U.S. federal government enacted the TCJA. The TCJA significantly changes U.S. corporate income tax law. Notable items impacting the effective tax rate for the 2018 tax year related to the TCJA include a rate reduction in the corporate tax rate to 21% from 35% and an increase in the estimated flow-through depreciation partially offset by the repeal of the manufacturer’s production deduction. In 2017, the Company recognized the income tax effects of the TCJA in accordance with Staff Accounting Bulletin No. 118 (“SAB 118”) which provides SEC guidance on the application of ASC 740, Income Taxes, in the reporting period in which the TCJA was signed into law. Accordingly, the Company’s financial statements reflected the income tax effects of U.S. tax reform for which the accounting was complete and provisional amounts for those impacts for which the accounting under ASC 740 was incomplete, but a reasonable estimate could be determined. The Company has completed its calculation of the impact of the TCJA in its income tax provision during the year ended December 31, 2018 in accordance with its understanding of the TCJA and guidance available as of the date of this filing, and as a result recognized $0.0 million and $0.2 million of discrete tax expense in the fourth quarters of 2018 and 2017 , respectively. This total results from the remeasurement of certain deferred tax assets and liabilities from 35% to 21% . The most material deferred taxes to be remeasured related to property, plant and equipment. The remeasurement of deferred tax assets and liabilities related to regulated utility property of $7.7 million and $215.5 million in 2018 and 2017 , respectively, was recorded as a regulatory liability, which was a non-cash adjustment.

Because of the impact of deferred tax accounting, other than interest and penalties, the timing of the deductions will not affect the annual effective tax rate but would accelerate the tax payments to an earlier period. Tax-related interest expense and income is reported as part of the provision for federal and state income taxes. Penalties, if incurred, would also be recognized as a component of tax expense. There are no interest or penalties applicable to the periods contained in this report. |

Benefit Plans | BENEFIT PLANS Defined Contribution Plans All of IPL’s employees are covered by one of two defined contribution plans, the Thrift Plan or the RSP: The Thrift Plan Approximately 85% of IPL’s active employees are covered by the Thrift Plan, a qualified defined contribution plan. All union new hires are covered under the Thrift Plan. Participants elect to make contributions to the Thrift Plan based on a percentage of their base compensation. Each participant’s contribution is matched up to certain thresholds of base compensation. The IBEW clerical-technical union new hires receive an annual lump sum company contribution into the Thrift Plan in addition to the company match. Employer contributions to the Thrift Plan were $3.3 million , $3.4 million and $3.1 million for 2018 , 2017 and 2016 , respectively. The RSP Approximately 15% of IPL’s active employees are covered by the RSP, a qualified defined contribution plan containing a match, nondiscretionary and profit sharing component. All non-union new hires are covered under the RSP. Participants elect to make contributions to the RSP based on a percentage of their eligible compensation. Each participant’s contribution is matched in amounts up to, but not exceeding, 5% of the participant’s eligible compensation. Starting in 2017 , the RSP also includes a 4% nondiscretionary contribution based as a percentage of each participant's eligible compensation. Finally, the RSP included a profit sharing component through 2016 whereby IPL contributed a percentage of each employee’s annual salary into the plan on a pre-tax basis. The profit sharing percentage was determined by the AES Board of Directors on an annual basis. Employer contributions (by IPL) relating to the RSP were $1.7 million , $1.8 million and $1.0 million for 2018 , 2017 and 2016 , respectively. Defined Benefit Plans Approximately 80% of IPL’s active employees are covered by the qualified Defined Benefit Pension Plan; while approximately 5% of active employees are IBEW clerical-technical unit employees who are only eligible for the Thrift Plan, which is a defined contribution plan. The remaining 15% of active employees are covered by the RSP. The RSP is a qualified defined contribution plan containing a profit sharing component. All non-union new hires are covered under the RSP, while IBEW physical unit union new hires are covered under the Defined Benefit Pension Plan and Thrift Plan. The IBEW clerical-technical unit new hires are no longer covered under the Defined Benefit Pension Plan but do receive an annual lump sum company contribution into the Thrift Plan, in addition to the company match. The Defined Benefit Pension Plan is noncontributory and is funded by IPL through a trust. Benefits for non-union participants in the Defined Benefit Pension Plan are based on salary, years of service and accrued benefits at April 1, 2015. Benefits for eligible union participants are based on each individual employee's pension band and years of service as opposed to their compensation. Pension bands are based primarily on job duties and responsibilities. Additionally, a small group of former officers and their surviving spouses are covered under a funded non-qualified Supplemental Retirement Plan. The total number of participants in the plan as of December 31, 2018 was 22 . The plan is closed to new participants. IPL also provides postretirement health care benefits to certain active or retired employees and the spouses of certain active or retired employees. Approximately 156 active employees and 10 retirees (including spouses) were receiving such benefits or entitled to future benefits as of January 1, 2018. The plan is unfunded. These postretirement health care benefits and the related unfunded obligation of $6.7 million and $7.0 million at December 31, 2018 and 2017 , respectively, were not material to the consolidated financial statements in the periods covered by this report. The following table presents information relating to the Pension Plans: Pension benefits 2018 2017 (In Thousands) Change in benefit obligation: Projected benefit obligation at January 1 $ 782,108 $ 731,825 Service cost 8,450 7,344 Interest cost 25,220 25,305 Actuarial (gain)/loss (62,303 ) 52,451 Amendments (primarily increases in pension bands) 5,446 900 Settlements — (266 ) Curtailments (1) 450 — Benefits paid (62,143 ) (35,451 ) Projected benefit obligation at December 31 697,228 782,108 Change in plan assets: Fair value of plan assets at January 1 738,947 674,430 Actual return on plan assets (22,404 ) 93,022 Employer contributions 30,085 7,212 Settlements — (266 ) Benefits paid (62,143 ) (35,451 ) Fair value of plan assets at December 31 684,485 738,947 Unfunded status $ (12,743 ) $ (43,161 ) Amounts recognized in the statement of financial position: Noncurrent liabilities $ (12,743 ) $ (43,161 ) Net amount recognized at end of year $ (12,743 ) $ (43,161 ) Sources of change in regulatory assets (2) : Prior service cost arising during period $ 5,446 $ 900 Net loss arising during period 902 4,101 Amortization of prior service cost (4,618 ) (4,240 ) Amortization of loss (11,403 ) (13,341 ) Total recognized in regulatory assets $ (9,673 ) $ (12,580 ) Amounts included in regulatory assets: Net loss $ 183,306 $ 193,807 Prior service cost 18,146 17,318 Total amounts included in regulatory assets $ 201,452 $ 211,125 (1) As a result of the announced AES restructuring in the first quarter of 2018, we recognized a plan curtailment of $1.2 million in the first quarter of 2018. (2) 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. Information for Pension Plans with a projected benefit obligation in excess of plan assets Pension benefits 2018 2017 (In Thousands) Benefit obligation $ 697,228 $ 782,108 Plan assets 684,485 738,947 Benefit obligation in excess of plan assets $ 12,743 $ 43,161 IPL’s total benefit obligation in excess of plan assets was $ 12.7 million as of December 31, 2018 ($ 11.6 million Defined Benefit Pension Plan and $1.1 million Supplemental Retirement Plan). Information for Pension Plans with an accumulated benefit obligation in excess of plan assets Pension benefits 2018 2017 (In Thousands) Accumulated benefit obligation $ 687,136 $ 769,678 Plan assets 684,485 738,947 Accumulated benefit obligation in excess of plan assets $ 2,651 $ 30,731 IPL’s total accumulated benefit obligation in excess of plan assets was $2.7 million as of December 31, 2018 ( $1.6 million Defined Benefit Pension Plan and $1.1 million Supplemental Retirement Plan). Significant Gains and Losses Related to Changes in the Benefit Obligation for the Period As shown in the table above, an actuarial gain of $62.3 million decreased the benefit obligation for the year ended December 31, 2018 and an actuarial loss of $52.5 million increased the benefit obligation for the year ended December 31, 2017. The actuarial gain in 2018 was primarily due to an increase in the discount rate, while the actuarial loss in 2017 was primarily due to a decrease in the discount rate. Pension Benefits and Expense Reported expenses relevant to the Defined Benefit Pension Plan are dependent upon numerous factors resulting from actual plan experience and assumptions of future experience, including the performance of plan assets and actual benefits paid out in future years. Pension costs associated with the Defined Benefit Pension Plan are impacted by the level of contributions made to the plan, earnings on plan assets, the adoption of new mortality tables, and employee demographics, including age, job responsibilities, salary and employment periods. Changes made to the provisions of the Defined Benefit Pension Plan may impact current and future pension costs. Pension costs may also be significantly affected by changes in key actuarial assumptions, including anticipated rates of return on plan assets and the corporate bond discount rates, as well as, the adoption of a new mortality table used in determining the projected benefit obligation and pension costs. The 2018 net actuarial loss of $0.9 million recognized in regulatory assets is comprised of two parts: (1) a $63.2 million pension asset actuarial loss primarily due to lower than expected return on assets; partially offset by (2) a $62.3 million pension liability actuarial gain primarily due to an increase in the discount rate used to value pension liabilities. The unrecognized net loss of $183.3 million in the Pension Plans has accumulated over time primarily due to the long-term declining trend in corporate bond rates, the lower than expected return on assets during the year 2008, and the adoption of new mortality tables which increased the expected benefit obligation due to the longer expected lives of plan participants, since ASC 715 was adopted. During 2018, the accumulated net loss declined due to higher discount rates used to value pension liabilities; which was partially offset by a combination of lower than expected return on pension assets, as well as the year 2018 amortization of accumulated loss. The unrecognized net loss, to the extent that it exceeds 10% of the greater of the benefit obligation or the assets, will be amortized and included as a component of net periodic benefit cost in future years. The amortization period is approximately 10.17 years based on estimated demographic data as of December 31, 2018 . The projected benefit obligation of $697.2 million less the fair value of assets of $684.5 million results in an unfunded status of $12.7 million at December 31, 2018 . Pension benefits for 2018 2017 2016 (In Thousands) Components of net periodic benefit cost: Service cost $ 8,450 $ 7,344 $ 7,018 Interest cost 25,220 25,305 25,815 Expected return on plan assets (40,801 ) (44,672 ) (43,492 ) Amortization of prior service cost 3,837 4,240 5,183 Recognized actuarial loss 11,403 13,195 13,896 Recognized settlement loss 1,230 146 — Total pension cost 9,339 5,558 8,420 Less: amounts capitalized 1,223 845 1,187 Amount charged to expense $ 8,116 $ 4,713 $ 7,233 Rates relevant to each year’s expense calculations: Discount rate – defined benefit pension plan 3.67 % 4.29 % 4.42 % Discount rate – supplemental retirement plan 3.60 % 4.00 % 4.19 % Expected return on defined benefit pension plan assets 5.45 % 6.75 % 6.75 % Expected return on supplemental retirement plan assets 5.45 % 6.75 % 6.75 % Pension expense for the following year is determined as of the December 31 measurement date based on the fair value of the Pension Plans’ assets, the expected long-term rate of return on plan assets, a mortality table assumption that reflects the life expectancy of plan participants, and a discount rate used to determine the projected benefit obligation. For 2018, pension expense was determined using an assumed long-term rate of return on plan assets of 5.45% . As of the December 31, 2018 measurement date, IPL increased the discount rate from 3.67% to 4.36% for the Defined Benefit Pension Plan and increased the discount rate from 3.60% to 4.24% for the Supplemental Retirement Plan. The discount rate assumptions affect the pension expense determined for 2019. In addition, IPL reduced the expected long-term rate of return on plan assets from 5.45% to 4.50% effective January 1, 2019. The expected long-term rate of return assumption affects the pension expense determined for 2019. The effect on 2019 total pension expense of a 25 basis point increase and decrease in the assumed discount rate is $(1.2) million and $1.2 million , respectively. In determining the discount rate to use for valuing liabilities we use the market yield curve on high-quality fixed income investments as of December 31, 2018 . We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are discounted back to the measurement date using the appropriate spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve. Pension Plan Assets and Fair Value Measurements Pension plan assets consist of investments in equities (domestic and international), fixed income securities, and short-term securities. Differences between actual portfolio returns and expected returns may result in increased or reduced pension costs in future periods. Pension costs are determined as of the plans' measurement date of December 31, 2018 . Pension costs are determined for the following year based on the market value of pension plan assets, expected employer contributions, a discount rate used to determine the projected benefit obligation and the expected long-term rate of return on plan assets. Fair value is defined under ASC 820 as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded as earned. Dividends are recorded on the ex-dividend date. Net appreciation includes the Plans’ gains and losses on investments bought and sold, as well as held, during the year. A description of the valuation methodologies used for each major class of assets and liabilities measured at fair value follows: • All the Plans’ investments have quoted market prices and are categorized as Level 1 in the fair value hierarchy. • The Plans’ investments in U.S. government agency fixed income securities are valued from third-party pricing sources, but they generally do not represent transaction prices for the identical security in an active market nor does it represent data obtained from an exchange. The primary objective of the Plans’ is to provide a source of retirement income for its participants and beneficiaries, while the primary financial objective is to improve the unfunded status of the Plans’. A secondary financial objective is, where possible, to minimize pension expense volatility. The objective is based on a long-term investment horizon, so that interim fluctuations should be viewed with appropriate perspective. There can be no assurance that these objectives will be met. In establishing our expected long-term rate of return assumption, we utilize a methodology developed by the plan’s investment consultant who maintains a capital market assumption model that takes into consideration risk, return and correlation assumptions across asset classes. A combination of quantitative analysis of historical data and qualitative judgment is used to capture trends, structural changes and potential scenarios not reflected in historical data. The result of the analyses is a series of inputs that produce a picture of how the plan consultant believes portfolios are likely to behave through time. Capital market assumptions are intended to reflect the behavior of asset classes observed over several market cycles. Stress assumptions are also examined, since the characteristics of asset classes are constantly changing. A dynamic model is employed to manage the numerous assumptions required to estimate portfolio characteristics under different base currencies, time horizons and inflation expectations. The Plans’ consultant develops forward-looking, long-term capital market assumptions for risk, return and correlations for a variety of global asset classes, interest rates and inflation. These assumptions are created using a combination of historical analysis, current market environment assessment and by applying the consultant’s own judgment. The consultant then determines an equilibrium long-term rate of return. We then take into consideration the investment manager/consultant expenses, as well as any other expenses expected to be paid out of the Plans’ trust. Finally, we have the Plans’ actuary perform a tolerance test of the consultant’s equilibrium expected long-term rate of return. We use an expected long-term rate of return compatible with the actuary’s tolerance level.

Funding for the qualified Defined Benefit Pension Plan is based upon actuarially determined contributions that take into account the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds. From an ERISA funding perspective, IPL’s funded target liability percentage was estimated to be 114% . In general, IPL must contribute the normal service cost earned by active participants during the plan year; however, this amount can be offset by any surplus or credit balance carried by the Pension Plan. The normal cost is expected to be approximately $8.3 million in 2019 (including $2.8 million for plan expenses), which is expected to be fully offset by the surplus amount. Each year thereafter, if the Pension Plans’ underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over a seven-year period. IPL does not expect to make an employer contribution for the calendar year 2019. IPL’s funding policy for the Pension Plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes. Benefit payments made from the Pension Plans for the years ended December 31, 2018 , 2017 and 2016 were $62.1 million , $35.5 million and $34.6 million , respectively. Expected benefit payments are expected to be paid out of the Pension Plans as follows: Year Pension Benefits (In Thousands) 2019 $ 39,780 2020 41,400 2021 42,956 2022 44,051 2023 44,659 2024 through 2028 230,608 |

Benefit Plans | BENEFIT PLANS Defined Contribution Plans All of IPL’s employees are covered by one of two defined contribution plans, the Thrift Plan or the RSP: The Thrift Plan Approximately 85% of IPL’s active employees are covered by the Thrift Plan, a qualified defined contribution plan. All union new hires are covered under the Thrift Plan. Participants elect to make contributions to the Thrift Plan based on a percentage of their base compensation. Each participant’s contribution is matched up to certain thresholds of base compensation. The IBEW clerical-technical union new hires receive an annual lump sum company contribution into the Thrift Plan in addition to the company match. Employer contributions to the Thrift Plan were $3.3 million , $3.4 million and $3.1 million for 2018 , 2017 and 2016 , respectively. The RSP Approximately 15% of IPL’s active employees are covered by the RSP, a qualified defined contribution plan containing a match, nondiscretionary and profit sharing component. All non-union new hires are covered under the RSP. Participants elect to make contributions to the RSP based on a percentage of their eligible compensation. Each participant’s contribution is matched in amounts up to, but not exceeding, 5% of the participant’s eligible compensation. Starting in 2017 , the RSP also includes a 4% nondiscretionary contribution based as a percentage of each participant's eligible compensation. Finally, the RSP included a profit sharing component through 2016 whereby IPL contributed a percentage of each employee’s annual salary into the plan on a pre-tax basis. The profit sharing percentage was determined by the AES Board of Directors on an annual basis. Employer contributions (by IPL) relating to the RSP were $1.7 million , $1.8 million and $1.0 million for 2018 , 2017 and 2016 , respectively. Defined Benefit Plans Approximately 80% of IPL’s active employees are covered by the qualified Defined Benefit Pension Plan; while approximately 5% of active employees are IBEW clerical-technical unit employees who are only eligible for the Thrift Plan, which is a defined contribution plan. The remaining 15% of active employees are covered by the RSP. The RSP is a qualified defined contribution plan containing a profit sharing component. All non-union new hires are covered under the RSP, while IBEW physical unit union new hires are covered under the Defined Benefit Pension Plan and Thrift Plan. The IBEW clerical-technical unit new hires are no longer covered under the Defined Benefit Pension Plan but do receive an annual lump sum company contribution into the Thrift Plan, in addition to the company match. The Defined Benefit Pension Plan is noncontributory and is funded by IPL through a trust. Benefits for non-union participants in the Defined Benefit Pension Plan are based on salary, years of service and accrued benefits at April 1, 2015. Benefits for eligible union participants are based on each individual employee's pension band and years of service as opposed to their compensation. Pension bands are based primarily on job duties and responsibilities. Additionally, a small group of former officers and their surviving spouses are covered under a funded non-qualified Supplemental Retirement Plan. The total number of participants in the plan as of December 31, 2018 was 22 . The plan is closed to new participants. IPL also provides postretirement health care benefits to certain active or retired employees and the spouses of certain active or retired employees. Approximately 156 active employees and 10 retirees (including spouses) were receiving such benefits or entitled to future benefits as of January 1, 2018. The plan is unfunded. These postretirement health care benefits and the related unfunded obligation of $6.7 million and $7.0 million at December 31, 2018 and 2017 , respectively, were not material to the consolidated financial statements in the periods covered by this report. The following table presents information relating to the Pension Plans: Pension benefits 2018 2017 (In Thousands) Change in benefit obligation: Projected benefit obligation at January 1 $ 782,108 $ 731,825 Service cost 8,450 7,344 Interest cost 25,220 25,305 Actuarial (gain)/loss (62,303 ) 52,451 Amendments (primarily increases in pension bands) 5,446 900 Curtailments (1) 450 — Settlements — (266 ) Benefits paid (62,143 ) (35,451 ) Projected benefit obligation at December 31 697,228 782,108 Change in plan assets: Fair value of plan assets at January 1 738,947 674,430 Actual return on plan assets (22,404 ) 93,022 Employer contributions 30,085 7,212 Settlements — (266 ) Benefits paid (62,143 ) (35,451 ) Fair value of plan assets at December 31 684,485 738,947 Unfunded status $ (12,743 ) $ (43,161 ) Amounts recognized in the statement of financial position: Noncurrent liabilities $ (12,743 ) $ (43,161 ) Net amount recognized at end of year $ (12,743 ) $ (43,161 ) Sources of change in regulatory assets (2) : Prior service cost arising during period $ 5,446 $ 900 Net loss arising during period 902 4,101 Amortization of prior service cost (4,618 ) (4,240 ) Amortization of loss (11,403 ) (13,341 ) Total recognized in regulatory assets $ (9,673 ) $ (12,580 ) Amounts included in regulatory assets: Net loss $ 183,306 $ 193,807 Prior service cost 18,146 17,318 Total amounts included in regulatory assets $ 201,452 $ 211,125 (1) As a result of the announced AES restructuring in the first quarter of 2018, we recognized a plan curtailment of $1.2 million in the first quarter of 2018. (2) 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. Information for Pension Plans with a projected benefit obligation in excess of plan assets Pension benefits 2018 2017 (In Thousands) Benefit obligation $ 697,228 $ 782,108 Plan assets 684,485 738,947 Benefit obligation in excess of plan assets $ 12,743 $ 43,161 IPL’s total benefit obligation in excess of plan assets was $12.7 million as of December 31, 2018 ( $11.6 million Defined Benefit Pension Plan and $1.1 million Supplemental Retirement Plan). Information for Pension Plans with an accumulated benefit obligation in excess of plan assets Pension benefits 2018 2017 (In Thousands) Accumulated benefit obligation $ 687,136 $ 769,678 Plan assets 684,485 738,947 Accumulated benefit obligation in excess of plan assets $ 2,651 $ 30,731 IPL’s total accumulated benefit obligation in excess of plan assets was $2.7 million as of December 31, 2018 ( $1.6 million Defined Benefit Pension Plan and $1.1 million Supplemental Retirement Plan). Significant Gains and Losses Related to Changes in the Benefit Obligation for the Period As shown in the table above, an actuarial gain of $62.3 million decreased the benefit obligation for the year ended December 31, 2018 and an actuarial loss of $52.5 million increased the benefit obligation for the year ended December 31, 2017. The actuarial gain in 2018 was primarily due to an increase in the discount rate, while the actuarial loss in 2017 was primarily due to a decrease in the discount rate. Pension Benefits and Expense Reported expenses relevant to the Defined Benefit Pension Plan are dependent upon numerous factors resulting from actual plan experience and assumptions of future experience, including the performance of plan assets and actual benefits paid out in future years. Pension costs associated with the Defined Benefit Pension Plan are impacted by the level of contributions made to the plan, earnings on plan assets, the adoption of new mortality tables, and employee demographics, including age, job responsibilities, salary and employment periods. Changes made to the provisions of the Defined Benefit Pension Plan may impact current and future pension costs. Pension costs may also be significantly affected by changes in key actuarial assumptions, including anticipated rates of return on plan assets and the corporate bond discount rates, as well as, the adoption of a new mortality table used in determining the projected benefit obligation and pension costs. The 2018 net actuarial loss of $0.9 million recognized in regulatory assets is comprised of two parts: (1) a $63.2 million pension asset actuarial loss primarily due to lower than expected return on assets; partially offset by (2) a $62.3 million pension liability actuarial gain primarily due to an increase in the discount rate used to value pension liabilities. The unrecognized net loss of $183.3 million in the Pension Plans has accumulated over time primarily due to the long-term declining trend in corporate bond rates, the lower than expected return on assets during the year 2008, and the adoption of new mortality tables which increased the expected benefit obligation due to the longer expected lives of plan participants, since ASC 715 was adopted. During 2018, the accumulated net loss declined due to higher discount rates used to value pension liabilities, which was partially offset by a combination of lower than expected return on pension assets, as well as the year 2018 amortization of accumulated loss. The unrecognized net loss, to the extent that it exceeds 10% of the greater of the benefit obligation or the assets, will be amortized and included as a component of net periodic benefit cost in future years. The amortization period is approximately 10.17 years based on estimated demographic data as of December 31, 2018 . The projected benefit obligation of $697.2 million less the fair value of assets of $684.5 million results in an unfunded status of $12.7 million at December 31, 2018 . Pension benefits for 2018 2017 2016 (In Thousands) Components of net periodic benefit cost: Service cost $ 8,450 $ 7,344 $ 7,018 Interest cost 25,220 25,305 25,815 Expected return on plan assets (40,801 ) (44,672 ) (43,492 ) Amortization of prior service cost 3,837 4,240 5,183 Recognized actuarial loss 11,403 13,195 13,896 Recognized settlement loss 1,230 146 — Total pension cost 9,339 5,558 8,420 Less: amounts capitalized 1,223 845 1,187 Amount charged to expense $ 8,116 $ 4,713 $ 7,233 Rates relevant to each year’s expense calculations: Discount rate – defined benefit pension plan 3.67 % 4.29 % 4.42 % Discount rate – supplemental retirement plan 3.60 % 4.00 % 4.19 % Expected return on defined benefit pension plan assets 5.45 % 6.75 % 6.75 % Expected return on supplemental retirement plan assets 5.45 % 6.75 % 6.75 % Pension expense for the following year is determined as of the December 31 measurement date based on the fair value of the Pension Plans’ assets, the expected long-term rate of return on plan assets, a mortality table assumption that reflects the life expectancy of plan participants, and a discount rate used to determine the projected benefit obligation. For 2018 , pension expense was determined using an assumed long-term rate of return on plan assets of 5.45% . As of the December 31, 2018 measurement date, IPL increased the discount rate from 3.67% to 4.36% for the Defined Benefit Pension Plan and increased the discount rate from 3.60% to 4.24% for the Supplemental Retirement Plan. The discount rate assumptions affect the pension expense determined for 2019. In addition, IPL reduced the expected long-term rate of return on plan assets from 5.45% to 4.50% effective January 1, 2019. The expected long-term rate of return assumption affects the pension expense determined for 2019 . The effect on 2019 total pension expense of a 25 basis point increase and decrease in the assumed discount rate is $(1.2) million and $1.2 million , respectively. In determining the discount rate to use for valuing liabilities we use the market yield curve on high-quality fixed income investments as of December 31, 2018 . We project the expected benefit payments under the plan based on participant data and based on certain assumptions concerning mortality, retirement rates, termination rates, etc. The expected benefit payments for each year are discounted back to the measurement date using the appropriate spot rate for each half-year from the yield curve, thereby obtaining a present value of all expected future benefit payments using the yield curve. Finally, an equivalent single discount rate is determined which produces a present value equal to the present value determined using the full yield curve. Pension Plan Assets and Fair Value Measurements Pension plan assets consist of investments in equities (domestic and international), fixed income securities, and short-term securities. Differences between actual portfolio returns and expected returns may result in increased or reduced pension costs in future periods. Pension costs are determined as of the plans' measurement date of December 31, 2018 . Pension costs are determined for the following year based on the market value of pension plan assets, expected employer contributions, a discount rate used to determine the projected benefit obligation and the expected long-term rate of return on plan assets. Fair value is defined under ASC 820 as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded as earned. Dividends are recorded on the ex-dividend date. Net appreciation includes the Plans’ gains and losses on investments bought and sold, as well as held, during the year. A description of the valuation methodologies used for each major class of assets and liabilities measured at fair value follows: • All the Plans’ investments have quoted market prices and are categorized as Level 1 in the fair value hierarchy. • The Plans’ investments in U.S. government agency fixed income securities are valued from third-party pricing sources, but they generally do not represent transaction prices for the identical security in an active market nor does it represent data obtained from an exchange. The primary objective of the Plans’ is to provide a source of retirement income for its participants and beneficiaries, while the primary financial objective is to improve the unfunded status of the Plans’. A secondary financial objective is, where possible, to minimize pension expense volatility. The objective is based on a long-term investment horizon, so that interim fluctuations should be viewed with appropriate perspective. There can be no assurance that these objectives will be met. In establishing IPL’s expected long-term rate of return assumption, we utilize a methodology developed by the plan’s investment consultant who maintains a capital market assumption model that takes into consideration risk, return and correlation assumptions across asset classes. A combination of quantitative analysis of historical data and qualitative judgment is used to capture trends, structural changes and potential scenarios not reflected in historical data. The result of the analyses is a series of inputs that produce a picture of how the plan consultant believes portfolios are likely to behave through time. Capital market assumptions are intended to reflect the behavior of asset classes observed over several market cycles. Stress assumptions are also examined, since the characteristics of asset classes are constantly changing. A dynamic model is employed to manage the numerous assumptions required to estimate portfolio characteristics under different base currencies, time horizons and inflation expectations. The Plans’ consultant develops forward-looking, long-term capital market assumptions for risk, return and correlations for a variety of global asset classes, interest rates and inflation. These assumptions are created using a combination of historical analysis, current market environment assessment and by applying the consultant’s own judgment. The consultant then determines an equilibrium long-term rate of return. IPL then takes into consideration the investment manager/consultant expenses, as well as any other expenses expected to be paid out of the Plans’ trust. Finally, IPL has the Plans’ actuary perform a tolerance test of the consultant’s equilibrium expected long-term rate of return. IPL uses an expected long-term rate of return compatible with the actuary’s tolerance level. The following table summarizes IPL’s target pension plan allocation for 2018 : Asset Category: Target Allocations Equity Securities 10% Debt Securities 90% Fair Value Measurements at December 31, 2018 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs Asset Category Total (Level 1) (Level 2) % Short-term investments $ 3,597 $ 3,597 $ — 1 % Mutual funds: U.S. equities 1,906 1,906 — — % International equities 52,354 52,354 — 8 % Fixed income 497,323 497,323 — 72 % Fixed income securities: U.S. Treasury securities 129,305 129,305 — 19 % Total $ 684,485 $ 684,485 $ — 100 % Fair Value Measurements at December 31, 2017 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs Asset Category Total (Level 1) (Level 2) % Short-term investments $ 115 $ 115 $ — — % Mutual funds: U.S. equities 162,144 162,144 — 22 % International equities 58,536 58,536 — 8 % Fixed income 415,868 415,868 — 56 % Fixed income securities: U.S. Treasury securities 102,284 102,284 — 14 % Total $ 738,947 $ 738,947 $ — 100 % Pension Funding IPL contributed $30.1 million , $7.2 million , and $16.0 million to the Pension Plans in 2018 , 2017 and 2016 , respectively. Funding for the qualified Defined Benefit Pension Plan is based upon actuarially determined contributions that take into account the amount deductible for income tax purposes and the minimum contribution required under ERISA, as amended by the Pension Protection Act of 2006, as well as targeted funding levels necessary to meet certain thresholds. From an ERISA funding perspective, IPL’s funded target liability percentage was estimated to be 114% . In general, IPL must contribute the normal service cost earned by active participants during the plan year; however, this amount can be offset by any surplus or credit balance carried by the Pension Plan. The normal cost is expected to be approximately $8.3 million in 2019 (including $2.8 million for plan expenses), which is expected to be fully offset by the surplus amount. Each year thereafter, if the Pension Plans' underfunding increases to more than the present value of the remaining annual installments, the excess is separately amortized over a seven-year period. IPL does not expect to make an employer contribution for the calendar year 2019. IPL’s funding policy for the Pension Plans is to contribute annually no less than the minimum required by applicable law, and no more than the maximum amount that can be deducted for federal income tax purposes. Benefit payments made from the Pension Plans for the years ended December 31, 2018 , 2017 and 2016 were $62.1 million , $35.5 million and $34.6 million , respectively. Expected benefit payments are expected to be paid out of the Pension Plans as follows: Year Pension Benefits (In Thousands) 2019 $ 39,780 2020 41,400 2021 42,956 2022 44,051 2023 44,659 2024 through 2028 230,608 |

Commitments and Contingencies | 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 regulated materials, including ash; the use and discharge of water used in generation boilers and for cooling purposes; 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 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. At this time, we cannot determine whether these NOVs could have a material impact on our business, financial condition and results of operations. We would seek recovery of any operating or capital expenditures, but not fines or penalties, related to air pollution control technology to reduce regulated air emissions; however, there can be no assurances that we would be successful. IPL has recorded a contingent liability related to these New Source Review cases and other CAA NOV matters. |

Business Segment Information | BUSINESS 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 "All Other" non-utility category primarily includes the Term Loan, 2020 IPALCO Notes and 2024 IPALCO Notes; approximately $6.4 million and $18.3 million of cash and cash equivalents, as of December 31, 2018 and 2017 , respectively; long-term investments of $4.0 million and $5.1 million as of December 31, 2018 and 2017 , respectively; and income taxes and interest related to those items.

Revenue from Contract with Customer [Text Block] | REVENUE Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. Retail revenues - IPL energy sales to utility customers are based on the reading of meters at the customer’s location that occurs on a systematic basis throughout the month. IPL sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Retail revenues have a single performance obligation, as the promise to transfer energy and other distribution and/or transmission services are not separately identifiable from other promises in the contracts and, therefore, are not distinct. Additionally, as the performance obligation is satisfied over time as energy is delivered, and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. In exchange for the exclusive right to sell or distribute electricity in our service area, IPL is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that IPL is allowed to charge customers for electric services. Since tariffs are approved by the regulator, the price that IPL has the right to bill corresponds directly with the value to the customer of IPL’s performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff. Customer payments are typically due on a monthly basis. Wholesale revenues - Power produced at the generation stations in excess of our retail load is sold into the MISO market. Such sales are made at either the day-ahead or real-time hourly market price, and these sales are classified as wholesale revenues. We sell to and purchase power from MISO, and such sales and purchases are settled and accounted for on a net hourly basis. In the MISO market, wholesale revenue is recorded at the spot price based on the quantities of MWh delivered in each hour during each month. As a member of MISO, we are obligated to declare the availability of our energy production into the wholesale energy market, but we are not obligated to commit our previously declared availability. As such, contract terms end as the energy for each day is delivered to the market in the case of the day-ahead market and for each hour in the case of the real-time market. Miscellaneous revenues - Miscellaneous revenues are mainly comprised of MISO transmission revenues. MISO transmission revenues are earned when IPL’s power lines are used in transmission of energy by power producers other than IPL. As IPL owns and operates transmission lines in central and southern Indiana, demand charges collected from network customers by MISO are allocated to the appropriate transmission owners (including IPL) and recognized as transmission revenues. Capacity revenues are also included in miscellaneous revenues, but these were not material for the period presented. Transmission revenues have a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that the transmission operator has the right to bill corresponds directly with the value to the customer of IPL’s performance completed in each period as the price paid is the transmission operators allocation of the tariff rate (as approved by the regulator) charged to network participants. IPL’s revenue from contracts with customers was $1,428.9 million for the year ended December 31, 2018 . The following table presents our revenue from contracts with customers and other revenue (in thousands): For the Year Ended, December 31, 2018 Retail Revenues Retail revenue from contracts with customers $ 1,380,042 Other retail revenues (1) 16,423 Wholesale Revenues 38,789 Miscellaneous Revenues Transmission and other revenue from contracts with customers 10,057 Other miscellaneous revenues (2) 5,194 Total Revenues $ 1,450,505 (1) Other retail revenue represents alternative revenue programs not accounted for under ASC 606 (2) Other miscellaneous revenue includes lease and other miscellaneous revenues not accounted for under ASC 606 The balances of receivables from contracts with customers are $160.8 million and $155.7 million as of December 31, 2018 and January 1, 2018, respectively. Payment terms for all receivables from contracts with customers are typically within 30 days. The Company has elected to apply the optional disclosure exemptions under ASC 606. Therefore, the Company has not included disclosure pertaining to revenue expected to be recognized in any future year related to remaining performance obligations, as we exclude contracts with an original length of one year or less, contracts for which we recognize revenue based on the amount we have the right to invoice for services performed, and contracts with variable consideration allocated entirely to a wholly unsatisfied performance obligation when the consideration relates specifically to our efforts to satisfy the performance obligation and depicts the amount to which we expect to be entitled. |

Capacity revenues are also included in miscellaneous revenues, but these were not material for the period presented. Transmission revenues have a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that the transmission operator has the right to bill corresponds directly with the value to the customer of IPL’s performance completed in each period as the price paid is the transmission operators allocation of the tariff rate (as approved by the regulator) charged to network participants. IPL’s revenue from contracts with customers was $1,428.9 million for the year ended December 31, 2018 . The following table presents IPL's revenue from contracts with customers and other revenue (in thousands): For the Year Ended, December 31, 2018 Retail Revenues Retail revenue from contracts with customers $ 1,380,042 Other retail revenues (1) 16,423 Wholesale Revenues 38,789 Miscellaneous Revenues Transmission and other revenue from contracts with customers 10,057 Other miscellaneous revenues (2) 5,194 Total Revenues $ 1,450,505 (1) Other retail revenue represents alternative revenue programs not accounted for under ASC 606 (2) Other miscellaneous revenue includes lease and other miscellaneous revenues not accounted for under ASC 606 The balances of receivables from contracts with customers are $160.8 million and $155.7 million as of December 31, 2018 and January 1, 2018, respectively. Payment terms for all receivables from contracts with customers are typically within 30 days. IPL has elected to apply the optional disclosure exemptions under ASC 606. Therefore, IPL has not included disclosure pertaining to revenue expected to be recognized in any future year related to remaining performance obligations, as we exclude contracts with an original length of one year or less, contracts for which we recognize revenue based on the amount we have the right to invoice for services performed, and contracts with variable consideration allocated entirely to a wholly unsatisfied performance obligation when the consideration relates specifically to our efforts to satisfy the performance obligation and depicts the amount to which IPL expects to be entitled. |

Schedule I - Condensed Financial Information Of Registrant | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Accounting for Subsidiaries and Affiliates – IPALCO has accounted for the earnings of its subsidiaries on the equity method in the unconsolidated condensed financial information. EQUITY Paid In Capital and Capital Stock 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 interest in IPALCO was 30% . On June 1, 2016, IPALCO received equity capital contributions of (i) $64.8 million from AES U.S. Investments and (ii) $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. DEBT The following table presents IPALCO’s long-term indebtedness: December 31, Series Due 2018 2017 (In Thousands) Long-Term Debt Term Loan July 2020 $ 65,000 $ — 3.45% Senior Secured Notes July 2020 — 405,000 405,000 3.70% Senior Secured Notes September 2024 — 405,000 405,000 Unamortized discount – net (424 ) (534 ) Deferred financing costs – net (5,696 ) (7,863 ) Total long-term debt 868,880 801,603 Less: current portion of long-term debt — — Net long-term debt $ 868,880 $ 801,603 Long-Term Debt IPALCO Term Loan On October 31, 2018, IPALCO closed on a new Term Loan consisting of a $65 million credit facility maturing July 1, 2020. The term Loan is variable rate and is secured by IPALCO’s pledge of all the outstanding common stock of IPL. The lien on the pledged shares is shared equally and ratably with IPALCO’s existing senior secured notes. The Term Loan proceeds were used to repay amounts due under IPL's Credit Agreement and for general corporate purposes. IPALCO’s Senior Secured Notes In August 2017, IPALCO completed the sale of the $405 million 2024 IPALCO Notes pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended. The 2024 IPALCO Notes were issued pursuant to an Indenture dated August 22, 2017, by and between IPALCO and U.S. Bank, National Association, as trustee. The 2024 IPALCO Notes were priced to the public at 99.901% of the principal amount. Net proceeds to IPALCO were approximately $399.3 million after deducting underwriting costs and estimated offering expenses. These costs are being amortized to the maturity date using the effective interest method. We used the net proceeds from this offering, together with cash on hand, to redeem the $400 million 2018 IPALCO Notes on September 21, 2017, and to pay certain related fees, expenses and make-whole premiums. A loss on early extinguishment of debt of $8.9 million for the 2018 IPALCO Notes is included as a separate line item in the accompanying Unconsolidated Statements of Operations. The 2020 IPALCO Notes and 2024 IPALCO Notes are secured by IPALCO’s pledge of all of the outstanding common stock of IPL. The lien on the pledged shares is shared equally and ratably with IPALCO’s Term Loan. IPALCO also agreed to register the 2024 IPALCO Notes under the Securities Act by filing an exchange offer registration statement or, under specified circumstances, a shelf registration statement with the SEC pursuant to a Registration Rights Agreement that IPALCO entered into with Morgan Stanley & Co. LLC and PNC Capital Markets LLC, as representatives of the initial purchasers of the 2024 IPALCO Notes, dated August 22, 2017. IPALCO filed its registration statement on Form S-4 with respect to the 2024 IPALCO Notes with the SEC on November 13, 2017, and this registration statement was declared effective on December 5, 2017. The exchange offer was completed on January 12, 2018. |

Entity Information [Line Items] | |
Property, Plant and Equipment, Policy [Policy Text Block] | Utility Plant and Depreciation Utility plant is stated at original cost as defined for regulatory purposes. The cost of additions to utility plant and replacements of retirement units of property are charged to plant accounts. Units of property replaced or abandoned in the ordinary course of business are retired from the plant accounts at cost; such amounts, less salvage, are charged to accumulated depreciation. Depreciation is computed by the straight-line method based on functional rates approved by the IURC and averaged 4.2% , 4.1% , and 4.3% during 2018 , 2017 and 2016 , respectively. Depreciation expense was $235.2 million , $209.8 million , and $209.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. "Depreciation and amortization" expense on the accompanying Consolidated Statements of Operations is presented net of regulatory deferrals of depreciation expense and also includes amortization of intangible assets and amortization of previously deferred regulatory costs. |
Schedule of Accounts, Notes, Loans and Financing Receivable [Table Text Block] | The following table summarizes our accounts receivable balances at December 31: As of December 31, 2018 2017 (In Thousands) Accounts receivable, net Customer receivables $ 91,426 $ 94,168 Unbilled revenue 68,893 61,599 Amounts due from related parties 5,720 37 Other 4,341 4,640 Provision for uncollectible accounts (2,821 ) (2,830 ) Total accounts receivable, net $ 167,559 $ 157,614 |
Inventory, Policy [Policy Text Block] | Inventories We maintain coal, fuel oil, materials and supplies inventories for use in the production of electricity. These inventories are accounted for at the lower of cost or net realizable value, using the average cost. The following table summarizes our inventories balances at December 31: As of December 31, 2018 2017 (In Thousands) Inventories Fuel $ 32,457 $ 32,393 Materials and supplies 67,211 63,623 Total inventories $ 99,668 $ 96,016 |
Intangible Assets, Finite-Lived, Policy [Policy Text Block] | Intangible Assets Intangible assets primarily include capitalized software of $129.7 million and $99.4 million and its corresponding accumulated amortization of $88.8 million and $83.4 million , as of December 31, 2018 and 2017 , respectively. Amortization expense was $5.5 million , $4.3 million and $5.9 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The estimated amortization expense of this capitalized software is $30.2 million over the next 5 years ( $5.7 million in 2019, $6.9 million in 2020, $6.9 million in 2021, $6.9 million in 2022 and $3.8 million in 2023). |
Principles of Consolidation | Principles of Consolidation IPALCO’s consolidated financial statements are prepared in accordance with GAAP and in conjunction with the rules and regulations of the SEC. The consolidated financial statements include the accounts of IPALCO, its regulated utility subsidiary, IPL, and its unregulated subsidiary, Mid-America. All intercompany items have been eliminated in consolidation. Certain costs for shared resources amongst IPL and IPALCO, such as labor and benefits, are allocated to each entity based on allocation methodologies that management believes to be reasonable. We have evaluated subsequent events through the date this report is issued. |
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Financial Statement Presentation During 2018, we adopted a change in presentation on our Consolidated Balance Sheets and Consolidated Statements of Operations from a utility format to a traditional format. These changes combined or revised the order of certain balance sheet and income statement line items and resulted in the movement of certain immaterial balances within the Consolidated Statements of Operations and Consolidated Balance Sheets, but did not result in any material changes to the classification of any such amounts or have any impact on net assets or net income. Certain amounts from prior periods have been reclassified to conform to the current period presentation. |
Use of Management Estimates | 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 management is required to make. Actual results may differ from those estimates. |
Regulation | Regulatory Accounting The retail utility operations of IPL are subject to the jurisdiction of the IURC. IPL’s wholesale power transactions are subject to the jurisdiction of the FERC. These agencies regulate IPL’s utility business operations, tariffs, accounting, depreciation allowances, services, issuances of securities and the sale and acquisition of utility properties. The financial statements of IPL are based on GAAP, including the provisions of FASB ASC 980 “Regulated Operations,” which gives recognition to the ratemaking and accounting practices of these agencies. See also Note 5, “Regulatory Assets and Liabilities” for a discussion of specific regulatory assets and liabilities. |
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents. Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral. The following table provides a summary of cash, cash equivalents and restricted cash amounts as shown on the Consolidated Statements of Cash Flows: As of December 31, 2018 2017 (In Thousands) Cash, cash equivalents and restricted cash Cash and cash equivalents $ 33,199 $ 30,681 Restricted cash 400 — Total cash, cash equivalents and restricted cash $ 33,599 $ 30,681 |
Revenues and Accounts Receivable | Revenues and Accounts Receivable Revenues related to the sale of energy are generally recognized when service is rendered or energy is delivered to customers. However, the determination of the energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to certain customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making its estimates of unbilled revenue, IPL uses complex models that consider various factors including daily generation volumes; known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in future periods when revenue is billed. An allowance for potential credit losses is maintained and amounts are written off when normal collection efforts have been exhausted. Our provision for doubtful accounts included in “Operating expenses - Operation and maintenance” on the accompanying Consolidated Statements of Operations was $6.0 million , $5.9 million and $ 4.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. IPL’s basic rates include a provision for fuel costs as established in IPL’s most recent rate proceeding, which last adjusted IPL’s rates in December 2018. IPL is permitted to recover actual costs of purchased power and fuel consumed, subject to certain restrictions. This is accomplished through quarterly FAC proceedings, in which IPL estimates the amount of fuel and purchased power costs in future periods. Through these proceedings, IPL is also permitted to recover, in future rates, underestimated fuel and purchased power costs from prior periods, subject to certain restrictions, and therefore the over or underestimated costs are deferred or accrued and amortized into fuel expense in the same period that IPL’s rates are adjusted. See also Note 2, “ Regulatory Matters ” for a discussion of other costs that IPL is permitted to recover through periodic rate adjustment proceedings and the status of current rate adjustment proceedings. In addition, we are one of many transmission system owner members of MISO, a regional transmission organization which maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. See Note 13, " Revenue " for additional information of MISO sales and other revenue streams. The following table summarizes our accounts receivable balances at December 31: As of December 31, 2018 2017 (In Thousands) Accounts receivable, net Customer receivables $ 91,426 $ 94,168 Unbilled revenue 68,893 61,599 Amounts due from related parties 5,720 37 Other 4,341 4,640 Provision for uncollectible accounts (2,821 ) (2,830 ) Total accounts receivable, net $ 167,559 $ 157,614 |
Contingencies | Contingencies IPALCO accrues for loss contingencies when the amount of the loss is probable and estimable. IPL is subject to various environmental regulations, and is involved in certain legal proceedings. If IPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. As of December 31, 2018 and 2017 , total loss contingencies accrued were $4.6 million and $4.1 million , respectively, which were included in “Accrued and Other Current Liabilities” on the accompanying Consolidated Balance Sheets. |
Concentration of Risk | Concentrations of Risk Substantially all of IPL’s customers are located within the Indianapolis area. Approximately 68% of IPL’s full-time employees are covered by collective bargaining agreements in two bargaining units: a physical unit and a clerical-technical unit. IPL’s contract with the physical unit expires on December 6, 2021 , and the contract with the clerical-technical unit expires February 17, 2020 . Additionally, IPL has long-term coal contracts with four suppliers, with about 46% of our existing coal under contract for the three-year period ending December 31, 2021 coming from one supplier. Substantially all of the coal is currently mined in the state of Indiana. |
Allowance For Funds Used During Construction | Allowance For Funds Used During Construction In accordance with the Uniform System of Accounts prescribed by FERC, IPL capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. For the Eagle Valley CCGT, Harding Street refueling projects, and NPDES projects, IPL capitalized amounts using a pretax composite rate of 6.4% , 6.6% and 7.1% during 2018 , 2017 and 2016 , respectively. |
Derivatives | Derivatives We have only limited involvement with derivative financial instruments and do not use them for trading purposes. IPALCO accounts for its derivatives in accordance with ASC 815 “Derivatives and Hedging.” In addition, IPL has entered into contracts involving the physical delivery of energy and fuel. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, IPL has elected to account for them as accrual contracts, which are not adjusted for changes in fair value. |
Impairment of Long-Lived Assets | Impairment of Long-lived Assets GAAP requires that we measure long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our utility plant assets was $4.1 billion and $4.0 billion as of December 31, 2018 and 2017 , respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and generating and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; the anticipated demand and relative pricing of retail electricity in our service territory and wholesale electricity in the region; and the cost of fuel. |
Income Taxes | Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, and their respective income tax bases. The Company establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. The Company’s tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. The Company’s policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations. Income tax assets or liabilities which are includable in allowable costs for ratemaking purposes in future years are recorded as regulatory assets or liabilities with a corresponding deferred tax liability. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. |
Pension and Postretirement Benefits | Pension and Postretirement Benefits We recognize in our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes in the funded status, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans. We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans. |
Repair and Maintenance Costs | Repair and Maintenance Costs Repair and maintenance costs are expensed as incurred. |
Per Share Data | Per Share Data IPALCO is owned by AES U.S. Investments and CDPQ. IPALCO does not report earnings on a per-share basis. |
New Accounting Pronouncements | New Accounting Pronouncements Adopted in 2018 The following table provides a brief description of recent accounting pronouncements that had an impact on the Company’s consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2018-15, Intangibles— Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This standard aligns the accounting for implementation costs incurred for a cloud computing arrangement that is a service with the requirement for capitalizing implementation costs associated with developing or obtaining internal-use software. Transition method: retrospective or prospective. October 1, 2018 The Company elected to early-adopt this standard on a prospective basis, effective for fiscal year 2018. The adoption of this standard did not have a material impact on the financial statements. 2018-14, Compensation— Retirement Benefits— Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework This standard modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Transition method: retrospective. Early adoption elected, January 1, 2018. Impact limited to changes in financial statement disclosures. 2017-07, Compensation— This standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization. Transition method: retrospective for presentation of non-service cost expense and prospective for the change in capitalization. January 1, 2018 The adoption of this standard resulted in a $(2.0) million and $1.0 million reclassification of non-service pension costs (credits) from Operating Expenses - Operations and maintenance to Other income/(expense), net for 2017 and 2016, respectively. 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 No material impact upon adoption of the standard. 2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606) See discussion of the ASUs below. January 1, 2018 See impact upon adoption of the standard below. Adoption of ASC Topic 606, “ Revenue from Contracts with Customers ” On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers”, and its subsequent corresponding updates (“ASC 606”). Under this standard, 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 services. The Company applied the modified retrospective method of adoption to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, the Company reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. There was no cumulative effect to our January 1, 2018 Consolidated Balance Sheet resulting from the adoption of ASC 606. |

The following table provides a summary of cash, cash equivalents and restricted cash amounts as shown on the Consolidated Statements of Cash Flows: As of December 31, 2018 2017 (In Thousands) Cash, cash equivalents and restricted cash Cash and cash equivalents $ 26,834 $ 12,342 Restricted cash 400 — Total cash, cash equivalents and restricted cash $ 27,234 $ 12,342 |
Revenues and Accounts Receivable | Revenues and Accounts Receivable Revenues related to the sale of energy are generally recognized when service is rendered or energy is delivered to customers. However, the determination of the energy sales to individual customers is based on the reading of their meters, which occurs on a systematic basis throughout the month. At the end of each month, amounts of energy delivered to certain customers since the date of the last meter reading are estimated and the corresponding unbilled revenue is accrued. In making its estimates of unbilled revenue, IPL uses complex models that consider various factors including daily generation volumes; known amounts of energy usage by nearly all residential, small commercial and industrial customers; estimated line losses; and estimated customer rates based on prior period billings. Given the use of these models, and that customers are billed on a monthly cycle, we believe it is unlikely that materially different results will occur in future periods when revenue is billed. An allowance for potential credit losses is maintained and amounts are written off when normal collection efforts have been exhausted. IPL’s provision for doubtful accounts included in “ Operating expenses - Operation and maintenance” on the accompanying Consolidated Statements of Operations was $6.0 million , $5.9 million and $4.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. IPL’s basic rates include a provision for fuel costs as established in IPL’s most recent rate proceeding, which last adjusted IPL’s rates in December 2018. IPL is permitted to recover actual costs of purchased power and fuel consumed, subject to certain restrictions. This is accomplished through quarterly FAC proceedings, in which IPL estimates the amount of fuel and purchased power costs in future periods. Through these proceedings, IPL is also permitted to recover, in future rates, underestimated fuel and purchased power costs from prior periods, subject to certain restrictions, and therefore the over or underestimated costs are deferred or accrued and amortized into fuel expense in the same period that IPL’s rates are adjusted. See also Note 2, “ Regulatory Matters ” for a discussion of other costs that IPL is permitted to recover through periodic rate adjustment proceedings and the status of current rate adjustment proceedings. In addition, IPL is one of many transmission system owner members of MISO, a regional transmission organization which maintains functional control over the combined transmission systems of its members and manages one of the largest energy markets in the U.S. See Note 13, " Revenue " for additional information of MISO sales and other revenue streams. The following table summarizes our accounts receivable balances at December 31: As of December 31, 2018 2017 (In Thousands) Accounts receivable, net Customer receivables $ 91,426 $ 94,168 Unbilled revenue 68,893 61,599 Amounts due from related parties 6,030 125 Other 4,341 4,640 Provision for uncollectible accounts (2,821 ) (2,830 ) Total accounts receivable, net $ 167,869 $ 157,702 |
Contingencies | Contingencies IPL accrues for loss contingencies when the amount of the loss is probable and estimable. IPL is subject to various environmental regulations, and is involved in certain legal proceedings. If IPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. As of December 31, 2018 and 2017 , total loss contingencies accrued were $4.6 million and $4.1 million , respectively, which were included in “ Accrued and Other Current Liabilities” on the accompanying Consolidated Balance Sheets. |
Concentration of Risk | Concentrations of Risk Substantially all of IPL’s customers are located within the Indianapolis area. Approximately 68% of IPL’s full-time employees are covered by collective bargaining agreements in two bargaining units: a physical unit and a clerical-technical unit. IPL’s contract with the physical unit expires on December 6, 2021 , and the contract with the clerical-technical unit expires February 17, 2020 . Additionally, IPL has long-term coal contracts with four suppliers, with about 46% of our existing coal under contract for the three-year period ending December 31, 2021 coming from one supplier. Substantially all of the coal is currently mined in the state of Indiana. |
Allowance For Funds Used During Construction | Allowance For Funds Used During Construction In accordance with the Uniform System of Accounts prescribed by FERC, IPL capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. For the Eagle Valley CCGT, Harding Street refueling projects, and NPDES projects, IPL capitalized amounts using a pretax composite rate of 6.4% , 6.6% and 7.1% during 2018 , 2017 and 2016 , respectively. |
Derivatives | Derivatives IPL has only limited involvement with derivative financial instruments and do not use them for trading purposes. IPL accounts for its derivatives in accordance with ASC 815 “Derivatives and Hedging.” In addition, IPL has entered into contracts involving the physical delivery of energy and fuel. Because these contracts qualify for the normal purchases and normal sales scope exception in ASC 815, IPL has elected to account for them as accrual contracts, which are not adjusted for changes in fair value. |
Impairment of Long-Lived Assets | Impairment of Long-lived Assets GAAP requires that IPL measures long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, IPL is required to write down the asset to its fair value with a charge to current earnings. The net book value of IPL’s utility plant assets was $4.1 billion and $4.0 billion as of December 31, 2018 and 2017 , respectively. IPL does not believe any of these assets are currently impaired. In making this assessment, IPL considers such factors as: the overall condition and generating and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; the anticipated demand and relative pricing of retail electricity in its service territory and wholesale electricity in the region; and the cost of fuel. |
Income Taxes | Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities, and their respective income tax bases. IPL establishes a valuation allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. IPL’s tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. IPL’s policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations. Income tax assets or liabilities which are includable in allowable costs for ratemaking purposes in future years are recorded as regulatory assets or liabilities with a corresponding deferred tax liability. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. |
Pension and Postretirement Benefits | Pension and Postretirement Benefits IPL recognizes in its Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes in the funded status, that would otherwise be recognized in AOCI, recorded as a regulatory asset as this can be recovered through future rates. All plan assets are recorded at fair value. IPL follows the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans. IPL accounts for and discloses pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715, IPL applies a disaggregated discount rate approach for determining service cost and interest cost for its defined benefit pension plans and postretirement plans. |
Repair and Maintenance Costs | Repair and Maintenance Costs Repair and maintenance costs are expensed as incurred. |
Per Share Data | Per Share Data IPALCO owns all of the outstanding common stock of IPL. IPL does not report earnings on a per-share basis. |
New Accounting Pronouncements | New Accounting Pronouncements Adopted in 2018 The following table provides a brief description of recent accounting pronouncements that had an impact on IPL's consolidated financial statements. Accounting pronouncements not listed below were assessed and determined to be either not applicable or did not have a material impact on IPL's consolidated financial statements. New Accounting Standards Adopted ASU Number and Name Description Date of Adoption Effect on the financial statements upon adoption 2018-15, Intangibles— Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This standard aligns the accounting for implementation costs incurred for a cloud computing arrangement that is a service with the requirement for capitalizing implementation costs associated with developing or obtaining internal-use software. Transition method: retrospective or prospective. October 1, 2018 IPL elected to early-adopt this standard on a prospective basis, effective for fiscal year 2018. The adoption of this standard did not have a material impact on the financial statements. 2018-14, Compensation— Retirement Benefits— Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework This standard modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Transition method: retrospective. Early adoption elected, January 1, 2018. Impact limited to changes in financial statement disclosures. 2017-07, Compensation— This standard changes the presentation of non-service costs associated with defined benefit plans and updates the guidance so that only the service cost component will be eligible for capitalization. Transition method: retrospective for presentation of non-service cost expense and prospective for the change in capitalization. January 1, 2018 The adoption of this standard resulted in a $(2.0) million and $1.0 million reclassification of non-service pension costs (credits) from Operating Expenses - Operations and maintenance to Other income/(expense), net for 2017 and 2016, respectively. 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 No material impact upon adoption of the standard. 2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606) See discussion of the ASUs below. January 1, 2018 See impact upon adoption of the standard below. Adoption of ASC Topic 606, “ Revenue from Contracts with Customers ” On January 1, 2018, IPL adopted ASU 2014-09, “Revenue from Contracts with Customers”, and its subsequent corresponding updates (“ASC 606”). Under this standard, 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 services. IPL applied the modified retrospective method of adoption to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under the previous revenue recognition standard. For contracts that were modified before January 1, 2018, IPL reflected the aggregate effect of all modifications when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price. There was no cumulative effect to IPL's January 1, 2018 Consolidated Balance Sheet resulting from the adoption of ASC 606. New Accounting Pronouncements Issued But Not Yet Effective The following table provides a brief description of recent accounting pronouncements that could have a material impact on IPL's consolidated financial statements once adopted. Accounting pronouncements not listed below were assessed and determined to be either not applicable or are expected to have no material impact on IPL's 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 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities The standard updates the hedge accounting model to expand the ability to hedge nonfinancial and financial risk components, reduce complexity, and ease certain documentation and assessment requirements. When facts and circumstances are the same as at the previous quantitative test, a subsequent quantitative effectiveness test is not required. The standard also eliminates the requirement to separately measure and report hedge ineffectiveness. For cash flow hedges, this means that the entire change in the fair value of a hedging instrument will be recorded in other comprehensive income and amounts deferred will be reclassified to earnings in the same income statement line as the hedged item. Transition method: modified retrospective with the cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date. Prospective for presentation and disclosures. January 1, 2019. Early adoption is permitted. IPL is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2018-19, 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. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses as it is done today, except that the losses will be recognized as an allowance rather than a reduction in the amortized cost of the securities. Transition method: various. January 1, 2020 Early adoption is permitted only as of January 1, 2019. IPL is currently evaluating the impact of adopting the standard on its consolidated financial statements. 2016-02, 2018-01, 2018-10, 2018-11, 2018-20, Leases (Topic 842) See discussion of the ASUs below. January 1, 2019. Early adoption is permitted. IPL adopted the standard on January 1, 2019; see below for the evaluation of the impact of its adoption on its consolidated financial statements. ASU 2016-02 and its subsequent corresponding updates require lessees to recognize assets and liabilities for most leases, and recognize expenses in a manner similar to the current accounting method. For lessors, the guidance modifies the lease classification criteria and the accounting for sales-type and direct financing leases. The guidance also eliminates current real estate-specific provisions. The standard must be adopted using a modified retrospective approach. The FASB has provided an optional transition method, which IPL has elected, that allows entities to continue to apply the guidance in ASC 840 Leases to the comparative periods presented in the year of adoption. Under this transition method, IPL will apply the transition provisions starting on January 1, 2019. IPL has elected to apply a package of practical expedients that allow lessees and lessors not to reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842. These three practical expedients must be elected as a package and must be consistently applied to all leases. IPL has also elected to apply an optional transition practical expedient for land easements that allows an entity to continue applying its current accounting policy for all land easements that exist before the standard's effective date that were not previously accounted for under ASC 840. IPL established a task force focused on the identification of contracts that are under the scope of the new standard and the assessment and measurement of their corresponding right-of-use assets and related liabilities. Additionally, the implementation team has been working on the configuration of a lease accounting tool that will support the implementation and the subsequent accounting. The implementation team has also evaluated changes to our business processes, systems and controls to support recognition and disclosure under the new standard. Under ASC 842, it is expected that fewer contracts will contain a lease. However, due to the elimination of today's real estate-specific guidance and changes to certain lessor classification criteria, more leases will qualify as sales-type leases and direct financing leases. Under these two models, a lessor will derecognize the asset and will recognize a lease receivable. According to ASC 842, the lease receivable includes the fair value of the plant after the contract period but does not include any variable payment such as margin on the sale of energy. Therefore, the lease receivable could be significantly different than the carrying amount of the underlying asset at lease commencement. In such circumstances, the difference between the initially recognized lease receivable and the carrying amount of the underlying asset is recognized as a gain/loss at lease commencement. The adoption of ASC 842 did not have a material impact on IPL's consolidated financial statements |

Disaggregation of Revenue [Table Text Block] | IPL’s revenue from contracts with customers was $1,428.9 million for the year ended December 31, 2018 . The following table presents our revenue from contracts with customers and other revenue (in thousands): For the Year Ended, December 31, 2018 Retail Revenues Retail revenue from contracts with customers $ 1,380,042 Other retail revenues (1) 16,423 Wholesale Revenues 38,789 Miscellaneous Revenues Transmission and other revenue from contracts with customers 10,057 Other miscellaneous revenues (2) 5,194 Total Revenues $ 1,450,505 |
Revenue from Contract with Customer [Text Block] | REVENUE Revenue is primarily earned from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. Retail revenues - IPL energy sales to utility customers are based on the reading of meters at the customer’s location that occurs on a systematic basis throughout the month. IPL sells electricity directly to end-users, such as homes and businesses, and bills customers directly. Retail revenues have a single performance obligation, as the promise to transfer energy and other distribution and/or transmission services are not separately identifiable from other promises in the contracts and, therefore, are not distinct. Additionally, as the performance obligation is satisfied over time as energy is delivered, and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. In exchange for the exclusive right to sell or distribute electricity in our service area, IPL is subject to rate regulation by federal and state regulators. This regulation sets the framework for the prices (“tariffs”) that IPL is allowed to charge customers for electric services. Since tariffs are approved by the regulator, the price that IPL has the right to bill corresponds directly with the value to the customer of IPL’s performance completed in each period. Therefore, revenue under these contracts is recognized using an output method measured by the MWhs delivered each month at the approved tariff. Customer payments are typically due on a monthly basis. Wholesale revenues - Power produced at the generation stations in excess of our retail load is sold into the MISO market. Such sales are made at either the day-ahead or real-time hourly market price, and these sales are classified as wholesale revenues. We sell to and purchase power from MISO, and such sales and purchases are settled and accounted for on a net hourly basis. In the MISO market, wholesale revenue is recorded at the spot price based on the quantities of MWh delivered in each hour during each month. As a member of MISO, we are obligated to declare the availability of our energy production into the wholesale energy market, but we are not obligated to commit our previously declared availability. As such, contract terms end as the energy for each day is delivered to the market in the case of the day-ahead market and for each hour in the case of the real-time market. Miscellaneous revenues - Miscellaneous revenues are mainly comprised of MISO transmission revenues. MISO transmission revenues are earned when IPL’s power lines are used in transmission of energy by power producers other than IPL. As IPL owns and operates transmission lines in central and southern Indiana, demand charges collected from network customers by MISO are allocated to the appropriate transmission owners (including IPL) and recognized as transmission revenues. Capacity revenues are also included in miscellaneous revenues, but these were not material for the period presented. Transmission revenues have a single performance obligation, as transmission services represent a distinct service. Additionally, as the performance obligation is satisfied over time and the same method is used to measure progress, the performance obligation meets the criteria to be considered a series. The price that the transmission operator has the right to bill corresponds directly with the value to the customer of IPL’s performance completed in each period as the price paid is the transmission operators allocation of the tariff rate (as approved by the regulator) charged to network participants. IPL’s revenue from contracts with customers was $1,428.9 million for the year ended December 31, 2018 . The following table presents our revenue from contracts with customers and other revenue (in thousands): For the Year Ended, December 31, 2018 Retail Revenues Retail revenue from contracts with customers $ 1,380,042 Other retail revenues (1) 16,423 Wholesale Revenues 38,789 Miscellaneous Revenues Transmission and other revenue from contracts with customers 10,057 Other miscellaneous revenues (2) 5,194 Total Revenues $ 1,450,505 (1) Other retail revenue represents alternative revenue programs not accounted for under ASC 606 (2) Other miscellaneous revenue includes lease and other miscellaneous revenues not accounted for under ASC 606 The balances of receivables from contracts with customers are $160.8 million and $155.7 million as of December 31, 2018 and January 1, 2018, respectively. Payment terms for all receivables from contracts with customers are typically within 30 days. The Company has elected to apply the optional disclosure exemptions under ASC 606. Therefore, the Company has not included disclosure pertaining to revenue expected to be recognized in any future year related to remaining performance obligations, as we exclude contracts with an original length of one year or less, contracts for which we recognize revenue based on the amount we have the right to invoice for services performed, and contracts with variable consideration allocated entirely to a wholly unsatisfied performance obligation when the consideration relates specifically to our efforts to satisfy the performance obligation and depicts the amount to which we expect to be entitled. |
