THE AES CORPORATION

Notes to Condensed Consolidated Financial Statements

For the Three Months Ended March 31, 2019 and 2018

(Unaudited)

1. FINANCIAL STATEMENT PRESENTATION

Consolidation — In this Quarterly Report the terms “AES,” “the Company,” “us” or “we” refer to the consolidated entity, including its subsidiaries and affiliates. The terms “The AES Corporation” or “the Parent Company” refer only to the publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates. Furthermore, VIEs in which the Company has a variable interest have been consolidated where the Company is the primary beneficiary. Investments in which the Company has the ability to exercise significant influence, but not control, are accounted for using the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

Interim Financial Presentation — The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income, changes in equity and cash flows. The results of operations for the three months ended March 31, 2019, are not necessarily indicative of expected results for the year ending December 31, 2019. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2018 audited consolidated financial statements and notes thereto, which are included in the 2018 Form 10-K filed with the SEC on February 26, 2019 (the “2018 Form 10-K”).

Cash, Cash Equivalents, and Restricted Cash — The following table provides a summary of cash, cash equivalents, and restricted cash amounts reported on the Condensed Consolidated Balance Sheet that reconcile to the total of such amounts as shown on the Condensed Consolidated Statements of Cash Flows (in millions):

	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	1,426	$	1,166
Restricted cash	519		370
Debt service reserves and other deposits	430		467
Cash, Cash Equivalents, and Restricted Cash	$	2,375	$	2,003

New Accounting Pronouncements Adopted in 2019 — 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
2018-02, Income Statement — Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from AOCI	This amendment allows a reclassification of the stranded tax effects resulting from the implementation of the Tax Cuts and Jobs Act from AOCI to retained earnings at the election of the filer. Because this amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.	January 1, 2019	The Company has not elected to reclassify any amounts to retained earnings. The Company’s accounting policy for releasing the income tax effects from AOCI occurs on a portfolio basis.
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	The adoption of this standard resulted in a $4 million increase to retained earnings.

2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606)	ASC 606 was adopted by sPower on January 1, 2019. sPower was not required to adopt ASC 606 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. Under the previous revenue standard, the payment received by sPower for the transfer of Incentive Tax Credits related to projects was deferred and recognized in revenue over time. Under ASC 606, this payment is recognized at a point in time.	January 1, 2019	The adoption of this standard resulted in an $8 million increase to retained earnings attributable to the AES Corporation stockholders’ equity.
2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842)	See discussion of the ASU below.	January 1, 2019	See impact upon adoption of the standard below.

On January 1, 2019, the Company adopted ASC 842 Leases and its subsequent corresponding updates (“ASC 842”). Under this standard, lessees are required to recognize assets and liabilities for most leases on the balance sheet, 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 eliminates previous real estate-specific provisions.

Under ASC 842, fewer contracts contain a lease. However, due to the elimination of the real estate-specific guidance and changes to certain lessor classification criteria, more leases qualify as sales-type leases and direct financing leases. Under these two models, a lessor derecognizes the asset and recognizes a lease receivable. According to ASC 842, the lease receivable includes the fair value of the asset after the contract period, but does not include variable payments 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.

During the course of adopting ASC 842, the Company applied various practical expedients including:

• The package of practical expedients (applied to all leases) that allowed lessees and lessors not to reassess:

a. whether any expired or existing contracts are or contain leases,

b. lease classification for any expired or existing leases, and

c. whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842.

• The transition practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements, and

• The transition practical expedient for lessees that allowed businesses to not separate lease and non-lease components. The Company applied the practical expedient to all classes of underlying assets when valuing right-of-use assets and lease liabilities. Contracts where the Company is the lessor were separated between the lease and non-lease components.

The Company applied the modified retrospective method of adoption and elected 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 applied the transition provisions starting at the date of adoption. The cumulative effect of the adoption of ASC 842 on our January 1, 2019 Condensed Consolidated Balance Sheet was as follows (in millions):

Condensed Consolidated Balance Sheet	Balance at December 31, 2018		Adjustments Due to ASC 842		Balance at January 1, 2019
Assets
Other noncurrent assets	$	1,514	$	253	$	1,767
Liabilities
Accrued and other liabilities	962		27		989
Other noncurrent liabilities	2,723		226		2,949

The primary impact of adoption was due to the recognition of a right-of-use-asset and lease liability for an operating land lease in Panama associated with the Colon LNG power plant and regasification terminal.

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
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.

2. INVENTORY

The following table summarizes the Company’s inventory balances as of the periods indicated (in millions):

	March 31, 2019		December 31, 2018
Fuel and other raw materials	$	310	$	300
Spare parts and supplies	269		277
Total	$	579	$	577

3. ASSET RETIREMENT OBLIGATION

During the three months ended March 31, 2019, the Company decreased the asset retirement obligation at DPL by $23 million, resulting in a reduction to Cost of Sales on the Condensed Consolidated Statement of Operations as the related plants are no longer in service. This decrease was due to reductions in estimated closure costs associated with ash ponds and landfills. The Company uses the cost approach to determine the initial value of 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. Subsequent downward revisions of ARO liabilities are discounted using the market-based rates that existed when the liability was initially recognized.

4. FAIR VALUE

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. By virtue of these amounts being 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. For further information on our valuation techniques and policies, see Note 4—Fair Value in Item 8.—Financial Statements and Supplementary Data of our 2018 Form 10-K.

Recurring Measurements — The following table presents, by level within the fair value hierarchy, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in millions). For the Company’s investments in marketable debt securities, the security classes presented are determined based on the nature and risk of the security and are consistent with how the Company manages, monitors and measures its marketable securities:

The following table summarizes the significant unobservable inputs used for Level 3 derivative assets (liabilities) as of March 31, 2019 (in millions, except range amounts):

Type of Derivative	Fair Value			Unobservable Input	Amount or Range (Weighted Average)
Interest rate	$	(182	)	Subsidiaries’ credit spreads	1.78% - 4.43% (3.70%)
Foreign currency:
Argentine peso	194			Argentine peso to U.S. dollar currency exchange rate after one year	57 - 105 (85)
Commodity:

Total	$	14

For interest rate derivatives and foreign currency derivatives, increases (decreases) in the estimates of the Company’s own credit spreads would decrease (increase) the value of the derivatives in a liability position. For foreign currency derivatives, increases (decreases) in the estimate of the above exchange rate would increase (decrease) the value of the derivative.

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

AOCL is expected to decrease pre-tax income from continuing operations for the twelve months ended March 31, 2020 by $57 million, primarily due to interest rate derivatives.

6. FINANCING RECEIVABLES

Receivables with contractual maturities of greater than one year are considered financing receivables. The Company’s financing receivables are primarily related to amended agreements or government resolutions that are due from CAMMESA, the administrator of the wholesale electricity market in Argentina. The following table presents financing receivables by country as of the dates indicated (in millions):

	March 31, 2019		December 31, 2018
Argentina	$	97	$	93
Other	13		23
Total	$	110	$	116

Argentina — Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the operation of power plants which generate cash for payments of

12

these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. The Company accrues interest on these receivables once the recognition criteria have been met. The Company’s collection estimates are based on assumptions that it believes to be reasonable, but are inherently uncertain. Actual future cash flows could differ from these estimates.

7. INVESTMENTS IN AND ADVANCES TO AFFILIATES

Summarized Financial Information — The following table summarizes financial information of the Company’s 50%-or-less-owned affiliates that are accounted for using the equity method (in millions):

	Three Months Ended March 31,
50%-or-less-Owned Affiliates	2019			2018
Revenue	$	214		$	206
Operating margin	11			28
Net income (loss)	(21		)	12

8. DEBT

Recourse Debt

In March 2018, the Company purchased via tender offers $671 million aggregate principal of its existing 5.50% senior unsecured notes due in 2024 and $29 million of its existing 5.50% senior unsecured notes due in 2025. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $44 million for the three months ended March 31, 2018.

In March 2018, the Company issued $500 million aggregate principal of 4.00% senior notes due in 2021 and $500 million of 4.50% senior notes due in 2023. The Company used the proceeds from these issuances to purchase via tender offer in full the $228 million balance of its 8.00% senior notes due in 2020 and the $690 million balance of its 7.375% senior notes due in 2021. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $125 million for the three months ended March 31, 2018.

Non-Recourse Debt

During the three months ended March 31, 2019, the Company’s subsidiaries had the following significant debt transactions:

Subsidiary	Issuances		Repayments			Gain (Loss) on Extinguishment of Debt
Southland	$	161	$	—		$	—
Gener	550		(363		)	(10		)
Total	$	711	$	(363	)	$	(10	)

Non-Recourse Debt in Default — The current portion of non-recourse debt includes the following subsidiary debt in default as of March 31, 2019 (in millions).

Subsidiary	Primary Nature of Default	Debt in Default		Net Assets
AES Puerto Rico	Covenant	$	311	$	151
AES Ilumina (Puerto Rico)	Covenant	34		18
Total		$	345

The above defaults are not payment defaults. All of the subsidiary non-recourse debt defaults were triggered by failure to comply with covenants or other requirements contained in the non-recourse debt documents due to the bankruptcy of the offtaker.

The AES Corporation’s recourse debt agreements include cross-default clauses that will trigger if a subsidiary or group of subsidiaries for which the non-recourse debt is in default provides 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently completed fiscal quarters. As of March 31, 2019, the Company had no defaults which resulted in or were at risk of triggering a cross-default under the recourse debt of the Parent Company. In the event the Parent Company is not in compliance with the financial covenants of its senior secured revolving credit facility, restricted payments will be limited to regular quarterly shareholder dividends at the then-prevailing rate. Payment defaults and bankruptcy defaults would preclude the making of any restricted payments.

9. COMMITMENTS AND CONTINGENCIES

Guarantees, Letters of Credit and Commitments — In connection with certain project financings, acquisitions and dispositions, power purchases and other agreements, the Parent Company has expressly undertaken limited obligations and commitments, most of which will only be effective or will be terminated upon the occurrence of future events. In the normal course of business, the Parent Company has entered into various agreements, mainly guarantees and letters of credit, to provide financial or performance assurance to third parties on behalf of AES businesses. These agreements are entered into primarily to support or enhance the creditworthiness otherwise achieved by a business on a stand-alone basis, thereby facilitating the availability of sufficient credit to accomplish their intended business purposes. Most of the contingent obligations relate to future performance commitments which the Company or its businesses expect to fulfill within the normal course of business. The expiration dates of these guarantees vary from less than one year to more than 16 years.

The following table summarizes the Parent Company’s contingent contractual obligations as of March 31, 2019. Amounts presented in the following table represent the Parent Company’s current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees.

Contingent Contractual Obligations	Amount (in millions)		Number of Agreements	Maximum Exposure Range for Individual Agreements (in millions)
Guarantees and commitments	$	633	28	$0 — 157
Letters of credit under the unsecured credit facility	368		6	$1 — 247
Letters of credit under the senior secured credit facility	80		30	$0 — 32
Asset sale related indemnities (1)	27		1	$27
Total	$	1,108	65

_____________________________

⁽¹⁾  Excludes normal and customary representations and warranties in agreements for the sale of assets (including ownership in associated legal entities) where the associated risk is considered to be nominal.

During the three months ended March 31, 2019, the Company paid letter of credit fees ranging from 1% to 3% per annum on the outstanding amounts of letters of credit.

Contingencies

Environmental — The Company periodically reviews its obligations as they relate to compliance with environmental laws, including site restoration and remediation. For each period ended March 31, 2019 and December 31, 2018, the Company had recognized liabilities of $5 million for projected environmental remediation costs. Due to the uncertainties associated with environmental assessment and remediation activities, future costs of compliance or remediation could be higher or lower than the amount currently accrued. Moreover, where no liability has been recognized, it is reasonably possible that the Company may be required to incur remediation costs or make expenditures in amounts that could be material but could not be estimated as of March 31, 2019. In aggregate, the Company estimates the range of potential losses related to environmental matters, where estimable, to be up to $16 million. The amounts considered reasonably possible do not include amounts accrued as discussed above.

Litigation — The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company has recognized aggregate liabilities for all claims of approximately $55 million and $53 million as of March 31, 2019 and December 31, 2018, respectively. These amounts are reported on the Condensed Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent liabilities. A significant portion of these accrued liabilities relate to regulatory matters and commercial disputes in international jurisdictions. There can be no assurance that these accrued liabilities will be adequate to cover all existing and future claims or that we will have the liquidity to pay such claims as they arise.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material but could not be estimated as of March 31, 2019. The material contingencies where a loss is reasonably possible primarily include disputes with offtakers, suppliers and EPC contractors; alleged breaches of contract; alleged violation of laws and regulations; income tax and non-income tax matters with tax authorities; and regulatory matters. In aggregate, the Company estimates the range of potential losses, where estimable, related to these reasonably possible material contingencies to be between $79 million and $439 million. The amounts considered reasonably possible do not include the amounts accrued, as discussed above. These material contingencies do not include income tax-related contingencies which are considered part of our uncertain tax positions.

10. LEASES

LESSEE — The Company has operating and finance leases for energy production facilities, land, office space, transmission lines, vehicles and other operating equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term. The Company’s leases do not contain any material residual value guarantees, restrictive covenants or subleases.

Right-of-use assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and lease liabilities are recognized on commencement of the lease based on the present value of lease payments over the lease term. As our leases do not provide an implicit rate, we use the subsidiaries’ incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives that are paid or payable to the lessee at commencement. The lease term includes the option to extend or terminate the lease if it is reasonably certain that the option will be exercised. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable payments excluded from the right-of-use assets and lease liabilities are recognized as incurred.

Right-of-use assets are long term by nature. The following table summarizes the amounts recognized on the Condensed Consolidated Balance Sheets related to lease asset and liability balances as of the period indicated (in millions):

	Consolidated Balance Sheet Classification	March 31, 2019

Components of Lease Cost	Three Months Ended March 31, 2019
Operating lease cost	$	13
Variable and short-term lease costs	1
Total lease cost	$	14

Operating cash outflows from operating leases included in the measurement of lease liabilities were $14 million for the three months ended March 31, 2019. Operating and financing cash outflows from finance leases were immaterial, as were non-cash acquisitions of right-of-use assets in exchange for new lease liabilities for the three months ended March 31, 2019.

LESSOR — The Company has operating leases for certain generation contracts that contain provisions to provide capacity to a customer, which is a stand-ready obligation to deliver energy when required by the customer. Capacity payments are generally considered lease elements as they cover the majority of available output from a facility. The allocation of contract payments between the lease and non-lease elements is made at the inception of the lease. Minimum lease payments from such contracts are recognized as lease revenue on a straight-line basis over the lease term, whereas contingent rentals are recognized when earned. Lease revenue included in the Condensed Consolidated Statements of Operations was $153 million for the three months ended March 31, 2019, of which $25 million was related to variable lease payments.

The option to extend or terminate a lease is based on customary early termination provisions in the contract, such as payment defaults, bankruptcy, and lack of performance on energy delivery. The Company has not recognized any early terminations as of March 31, 2019. Variable lease payments resulting from energy generation in excess of the contracted amount are determined based on the contract and market conditions.

The following table shows the future minimum lease receipts as of March 31, 2019 for the remainder of 2019 through 2023 and thereafter (in millions):

On February 22, 2019, the Board of Directors declared a quarterly common stock dividend of $0.1365 per share payable on May 15, 2019, to shareholders of record at the close of business on May 1, 2019.

13. SEGMENTS

The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs. Using the accounting guidance on segment reporting, the Company determined that its four operating segments are aligned with its four reportable segments corresponding to its SBUs.

Corporate and Other — The results of the Fluence and Simple Energy equity affiliates are included in “Corporate and Other.” Also included are the results of the AES self-insurance company and corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation.

The Company uses Adjusted PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures;

17

(d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company’s internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company’s results.

Revenue and Adjusted PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, charges for certain management fees, and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.

_______________________

⁽¹⁾  Other non-regulated revenue primarily includes lease and derivative revenue not accounted for under ASC 606.

Contract Balances — The timing of revenue recognition, billings, and cash collections results in accounts receivable and contract liabilities. The contract liabilities from contracts with customers were $128 million and $109 million as of March 31, 2019 and December 31, 2018, respectively.

During the three months ended March 31, 2019 and 2018, we recognized revenue of $3 million and $22 million, respectively, that was included in the corresponding contract liability balance at the beginning of the periods.

A significant financing arrangement exists for our Mong Duong plant in Vietnam. The plant was constructed under a build, operate, and transfer contract and will be transferred to the Vietnamese government after the completion of a 25 year PPA. The performance obligation to construct the facility was substantially completed in 2015. Approximately $1.4 billion of contract consideration related to the construction, but not yet collected through the 25 year PPA, was reflected as a loan receivable as of March 31, 2019.

Remaining Performance Obligations — The transaction price allocated to remaining performance obligations represents future consideration for unsatisfied (or partially unsatisfied) performance obligations at the end of the reporting period. As of March 31, 2019, the aggregate amount of transaction price allocated to remaining performance obligations was $15 million, primarily consisting of fixed consideration for the sale of renewable energy credits (RECs) in long-term contracts in the U.S. We expect to recognize revenue on approximately one-fifth of the remaining performance obligations in 2019, with the remainder recognized thereafter.

For further information on our accounting policies concerning contract balances and remaining performance obligations, see Note 18—Revenue in Item 8.—Financial Statements and Supplementary Data of our 2018 Form 10-K.

15. OTHER INCOME AND EXPENSE

Other income generally includes gains on insurance recoveries in excess of property damage, gains on asset sales and liability extinguishments, favorable judgments on contingencies, gains on contract terminations, allowance for funds used during construction and other income from miscellaneous transactions. Other expense generally includes losses on asset sales and dispositions, losses on legal contingencies, defined benefit plan non-

19

service costs, and losses from other miscellaneous transactions. The components are summarized as follows (in millions):

		Three Months Ended March 31,
		2019		2018
Other Income	Gain on insurance proceeds (1)	$	23	$	—
	Allowance for funds used during construction (US Utilities)	1		5

16. INCOME TAXES

The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective tax rates for the three months ended March 31, 2019 and 2018 were 32% and 23%, respectively. The difference between the Company’s effective tax rates for the 2019 and 2018 periods and the U.S. statutory tax rate of 21% related primarily to U.S. taxes on foreign earnings, foreign tax rate differentials, the impacts of foreign currency fluctuations at certain foreign subsidiaries, and nondeductible expenses.

In the first quarter of 2019, the U.S. Treasury issued final regulations related to the one-time transition tax which further amended the guidance of the proposed regulations. As a result, we recorded $3 million of discrete tax expense in the first quarter.

In the first quarter of 2018, the Company completed the sale of its entire 51% equity interest in Masinloc, resulting in pre-tax gain of approximately $777 million. The sale resulted in approximately $155 million of discrete tax expense in the U.S. under the new GILTI provision, which subjects the earnings of foreign subsidiaries to current U.S. taxation to the extent those earnings exceed an allowable return. See Note 18—Held-for-Sale and Dispositions for details of the sale.

17. DISCONTINUED OPERATIONS

Due to a portfolio evaluation in the first half of 2016, management decided to pursue a strategic shift to reduce the Company's exposure to the Brazilian distribution market. During 2017, Eletropaulo, the Company’s remaining distribution business in Brazil, met the criteria to qualify as a discontinued operation and its results of operations were reported as such. The disposal of Eletropaulo was completed in June 2018. Prior to its classification as discontinued operations, Eletropaulo was reported in the South America SBU reportable segment.

18. HELD-FOR-SALE AND DISPOSITIONS

Held-for-Sale

Jordan — In February 2019, the Company entered into an agreement to sell its 36% ownership interest in two generation plants, IPP1 and IPP4, and a solar project under construction in Jordan for $86 million, plus capital contributions to the solar project of approximately $5 million. The sale of IPP1 and IPP4 is expected to close during the second quarter of 2019, and the sale of the solar project during the second half of 2019, once construction is completed. As of March 31, 2019, IPP1 and IPP4 were classified as held-for-sale, but did not meet the criteria to be reported as discontinued operations. The solar project under construction did not meet the held-for-sale criteria. On a consolidated basis, the carrying value of the plants held-for-sale as of March 31, 2019 was $105 million. Pre-tax income attributable to AES was immaterial for the three months ended March 31, 2019 and 2018. Jordan is reported in the Eurasia SBU reportable segment.

Shady Point — In December 2018, the Company entered into an agreement to sell Shady Point, a U.S. coal-fired generating facility, for $30 million, subject to customary purchase price adjustments. The sale is subject to regulatory approval and is expected to close during the second half of 2019. As of March 31, 2019, Shady Point was classified as held-for-sale, but did not meet the criteria to be reported as discontinued operations. Shady Point's carrying value as of March 31, 2019 was $30 million. Pre-tax income attributable to AES was immaterial for the three months ended March 31, 2019 and 2018. Shady Point is reported in the US and Utilities SBU reportable segment.

20

Redondo Beach — In October 2018, the Company entered into an agreement to sell land held by AES Redondo Beach, a gas-fired generating facility in California. The sale is expected to close during 2019. As of March 31, 2019, the $24 million carrying value of the land held by Redondo Beach was classified as held-for-sale. Redondo Beach is reported in the US and Utilities SBU reportable segment.

Dispositions

Masinloc — In March 2018, the Company completed the sale of its entire 51% equity interest in Masinloc for cash proceeds of $1.05 billion, resulting in a pre-tax gain on sale of $777 million after post-closing adjustments, subject to U.S. income tax. Masinloc consisted of a coal-fired generation plant in operation, a coal-fired generation plant under construction, and an energy storage facility all located in the Philippines. The sale did not meet the criteria to be reported as discontinued operations. Prior to its sale, Masinloc was reported in the Eurasia SBU reportable segment.

DPL peaker assets — In March 2018, DPL completed the sale of six of its combustion turbine and diesel-fired generation facilities and related assets ("DPL peaker assets") for total proceeds of $239 million, inclusive of estimated working capital and subject to customary post-closing adjustments, resulting in a loss on sale of $2 million. The sale did not meet the criteria to be reported as discontinued operations. Prior to their sale, the DPL peaker assets were reported in the US and Utilities SBU reportable segment.

Beckjord facility — In February 2018, DPL transferred its interest in Beckjord, a coal-fired generation facility retired in 2014, including its obligations to remediate the facility and its site. The transfer resulted in cash expenditures of $15 million, inclusive of disposal charges, and a loss on disposal of $12 million. Prior to the transfer, Beckjord was reported in the US and Utilities SBU reportable segment.

Advancion Energy Storage — In January 2018, the Company deconsolidated the AES Advancion energy storage development business and contributed it to the Fluence joint venture, resulting in a gain on sale of $23 million. Prior to the transfer, the AES Advancion energy storage development business was reported as part of Corporate and Other.

There was no pre-tax income attributable to AES for the three months ended March 31, 2019 associated with businesses disposed of during the three months ended March 31, 2018. Excluding any impairment charges or gain/loss on sale, pre-tax income attributable to AES of disposed businesses for the three months ended March 31, 2018 was as follows:

	Three Months Ended March 31,
(in millions)	2018
Masinloc	$	9
DPL peaker assets	7
Total	$	16

19. EARNINGS PER SHARE

Basic and diluted earnings per share are based on the weighted average number of shares of common stock and potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted earnings per share, includes the effects of dilutive RSUs and stock options. The effect of such potential common stock is computed using the treasury stock method.

The following table is a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation for income from continuing operations for the three months ended March 31, 2019 and 2018, where income represents the numerator and weighted average shares represent the denominator.

21

Three Months Ended March 31,	2019					2018
(in millions, except per share data)	Income		Shares	$ per Share		Income		Shares	$ per Share
BASIC EARNINGS PER SHARE
Income from continuing operations attributable to The AES Corporation common stockholders	$	154	663	$	0.23	$	685	661	$	1.04
EFFECT OF DILUTIVE SECURITIES
Stock options	—		1	—		—		—	—
Restricted stock units	—		3	—		—		2	(0.01		)
DILUTED EARNINGS PER SHARE	$	154	667	$	0.23	$	685	663	$	1.03

The calculation of diluted earnings per share excluded stock awards which would be anti-dilutive. The calculation of diluted earnings per share excluded 1 million and 6 million stock awards outstanding for the three months ended March 31, 2019 and 2018, respectively, that could potentially dilute basic earnings per share in the future.

20. SUBSEQUENT EVENTS

Alto Sertão III Acquisition — On April 9, 2019, the Company entered into an agreement to purchase from Renova Energia S.A. the Alto Sertão III Wind Complex as well as a pipeline of wind power projects in development in Brazil for approximately $130 million, subject to certain precedent conditions, customary purchase price adjustments, and the assumption of approximately $250 million of non-recourse debt. The transaction is expected to close in the second half of 2019.

Kilroot and Ballylumford Sale — On April 9, 2019, the Company entered into an agreement to sell its entire 100% interest in the Kilroot coal and oil-fired plant and energy storage facility and the Ballylumford gas-fired plant in the United Kingdom for approximately $120 million, subject to customary purchase price adjustments. The sale is subject to approval under EU merger regulations and is expected to close in 2019. The assets did not qualify as held-for-sale as of March 31, 2019. The Company expects to recognize a combined loss on sale and impairment of approximately $200 million in 2019. Kilroot and Ballylumford are reported in the Eurasia SBU reportable segment.

sPower — On April 18, 2019, the Company closed on the sale of approximately 48% of its interest in a portfolio of sPower’s operating assets for approximately $170 million, subject to customary purchase price adjustments. After the sale, the Company’s ownership interest in this portfolio of sPower’s operating assets decreased from 50% to approximately 26%. The sPower equity method investment is reported in the US and Utilities SBU reportable segment.

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

The condensed consolidated financial statements included in Item 1.—Financial Statements of this Form 10-Q and the discussions contained herein should be read in conjunction with our 2018 Form 10-K.

FORWARD-LOOKING INFORMATION

The following discussion may contain forward-looking statements regarding us, our business, prospects and our results of operations that are subject to certain risks and uncertainties posed by many factors and events that could cause our actual business, prospects and results of operations to differ materially from those that may be anticipated by such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those described in Item 1A.—Risk Factors and Item 7.—Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2018 Form 10-K and subsequent filings with the SEC. Readers are cautioned not to place undue reliance on these forward-looking statements which speak only as of the date of this report. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that may subsequently arise. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements. Readers are urged to carefully review and consider the various disclosures made by us in this report and in our other reports filed with the SEC that advise of the risks and factors that may affect our business.

Overview of Our Business — We are a diversified power generation and utility company organized into the following four market-oriented SBUs: US and Utilities (United States, Puerto Rico and El Salvador); South America (Chile, Colombia, Argentina and Brazil); MCAC (Mexico, Central America and the Caribbean); and Eurasia (Europe and Asia). For additional information regarding our business, see Item 1.—Business of our 2018 Form 10-K.

We have two lines of business. The first business line is generation, where we own and/or operate power plants to generate and sell power to customers such as utilities, industrial users and other intermediaries. The second business line is utilities, where we own and/or operate utilities to generate or purchase, distribute, transmit and sell electricity to end-user customers in the residential, commercial, industrial and governmental sectors within a defined service area. In certain circumstances, our utilities also generate and sell electricity on the wholesale market. The generation lines of business are reported within all four of our SBUs and the utilities lines of business are reported within our US and Utilities SBU.

23

Executive Summary

Compared with last year, diluted earnings per share decreased $0.80 to $0.23, primarily due to the 2018 net gain on sale of Masinloc and lower margin, partially offset by lower losses on extinguishment of debt and current period gains on insurance proceeds. The decrease in margin reflects the impact of asset sales and dispositions, lower generation in Argentina, and lower availability at the MCAC SBU, partially offset by higher regulated rates at the US and Utilities SBU.

Adjusted EPS, a non-GAAP measure, remained flat at $0.28, primarily due to lower margins reflecting the impact of asset sales and dispositions, offset by lower interest on Parent Company debt, current period gains on insurance proceeds, and a lower effective tax rate.

Overview of Q1 2019 Results and Strategic Performance

Strategic Priorities — We continue to improve the returns from our existing portfolio and position AES for long-term, sustainable growth. Our backlog continues to increase, driven by our focus on select markets and taking advantage of our cost competitiveness, scale, existing businesses and relationships.

• We are on track to attain investment grade ratings by 2020.

• We completed construction of 21 MW of new projects and signed long-term contracts for 494 MW of renewable capacity, increasing our backlog to 6.2 GW.

• We signed a 12-year agreement to sell up to 18 TBTU of LNG annually in the Caribbean, beginning in 2020.

• We agreed to sell our businesses in Jordan and the United Kingdom for $211 million. Once these transactions close, which is expected later this year, we will have operations in 13 countries, down from 28 in 2011.

Components of Revenue, Cost of Sales, and Operating Margin — Revenue includes revenue earned from the sale of energy from our utilities and the production and sale of energy from our generation plants, which are classified as regulated and non-regulated, respectively, on the Condensed Consolidated Statements of Operations. Revenue also includes the gains or losses on derivatives associated with the sale of electricity.

Cost of sales includes costs incurred directly by the businesses in the ordinary course of business. Examples include electricity and fuel purchases, operations and maintenance costs, depreciation and amortization expenses, bad debt expense and recoveries, and general administrative and support costs (including employee-related costs directly associated with the operations of the business). Cost of sales also includes the gains or losses on derivatives (including embedded derivatives other than foreign currency embedded derivatives) associated with the

25

purchase of electricity or fuel.

Operating margin is defined as revenue less cost of sales.

Consolidated Revenue and Operating Margin

Three Months Ended March 31, 2019

Revenue

(in millions)

Consolidated Revenue — Revenue decreased $90 million, or 3%, for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. Excluding the unfavorable FX impact of $53 million, primarily in South America, this decrease was driven by:

• $63 million in Eurasia primarily due to the sale of the Masinloc power plant in March 2018; and

• $16 million in South America mainly driven by lower generation in Argentina as well as the sale of Electrica Santiago and the transmission lines in 2018, partially offset by higher spot prices in Colombia and sales volumes in Brazil.

These unfavorable impacts were partially offset by an increase of $44 million in MCAC driven by the commencement of operations of the Colon combined cycle facility in September 2018.

Operating Margin

(in millions)

Consolidated Operating Margin — Operating margin decreased $70 million, or 11%, for the three months ended March 31, 2019, compared to the three months ended March 31, 2018. Lower costs in Argentina, as a result of the peso devaluation, caused a net favorable impact to FX of $3 million, with the remaining decrease driven by:

• $46 million in South America mostly due to the drivers discussed above;

• $28 million in MCAC due to the outage at Changuinola as a result of the tunnel inspection work and lower hydrology in Panama as compared to the prior year; and

• $23 million in Eurasia primarily due to the drivers discussed above.

These unfavorable impacts were partially offset by an increase of $21 million in US and Utilities mostly due to a revision to the ARO at DPL and the 2018 rate order at IPL.

Consolidated Results of Operations — Other

General and administrative expenses

General and administrative expenses decreased $10 million, or 18%, to $46 million for the three months ended March 31, 2019, compared to $56 million for the three months ended March 31, 2018, primarily due to reduced people costs and lower business development expenses.

Interest expense

Interest expense decreased $16 million, or 6%, to $265 million for the three months ended March 31, 2019, compared to $281 million for the three months ended March 31, 2018. This decrease is primarily due to the reduction of debt at the Parent Company.

Interest income

Interest income increased $3 million, or 4%, to $79 million for the three months ended March 31, 2019, compared to $76 million for the three months ended March 31, 2018 with no material drivers.

Loss on extinguishment of debt

Loss on extinguishment of debt decreased $160 million, or 94%, to $10 million for the three months ended March 31, 2019, compared to $170 million for the three months ended March 31, 2018. This decrease was primarily due to losses of $169 million at the Parent Company in 2018 resulting from the redemption of senior notes compared to losses of $10 million at Gener in 2019.

See Note 8—Debt included in Item 1.—Financial Statements of this Form 10-Q for further information.

Other income and expense

Other income increased $17 million to $30 million for the three months ended March 31, 2019, compared to $13 million for the three months ended March 31, 2018. This increase was primarily due to gains on insurance recoveries associated with property damage at the Andres facility, partially offset by a decrease in the allowance for equity funds used during construction at IPALCO as a result of decreased construction activity.

Other expense increased $3 million, or 33%, to $12 million for the three months ended March 31, 2019, compared to $9 million for the three months ended March 31, 2018 with no material drivers.

See Note 15—Other Income and Expense included in Item 1.—Financial Statements of this Form 10-Q for further information.

Gain (loss) on disposal and sale of business interests

Gain on disposal and sale of business interests decreased to a loss of $4 million for the three months ended March 31, 2019 as compared to a gain of $788 million for the three months ended March 31, 2018 primarily due to the gain on sale of Masinloc in 2018.

See Note 18—Held-for-Sale and Dispositions included in Item 1.—Financial Statements of this Form 10-Q for further information.

___________________________________________

⁽¹⁾  Includes $4 million of gains and $13 million of losses on foreign currency derivative contracts for the three months ended March 31, 2019 and 2018, respectively.

The Company recognized net foreign currency transaction losses of $4 million for the three months ended March 31, 2019, primarily due to losses at the Parent Company resulting from the depreciation of intercompany receivables denominated in Euros.

27

The Company recognized net foreign currency transaction losses of $19 million for the three months ended March 31, 2018, primarily due to the devaluation of the Argentine peso, losses on derivatives related to Argentine government receivables, and mark-to-market losses on foreign currency derivatives in Colombia. These losses were partially offset by gains at the Parent Company due to the appreciation of intercompany receivables denominated in Euros and the British Pound.

Income tax expense

Income tax expense decreased $116 million, or 50%, to $115 million for the three months ended March 31, 2019, compared to $231 million for the three months ended March 31, 2018. The Company’s effective tax rates were 32% and 23% for the three months ended March 31, 2019 and 2018, respectively. This net increase was primarily due to the 2018 impact of the sale of the Company’s entire 51% equity interest in Masinloc. See Note 18— Held-for-Sale and Dispositions and Note 16—Income Taxes included in Item 1.—Financial Statements of this Form 10-Q for details and impacts of the sale.

Our effective tax rate reflects the tax effect of significant operations outside the U.S. which are generally taxed at rates different than the U.S. statutory rate of 21%. Furthermore, our foreign earnings may be subjected to incremental U.S. taxation under the GILTI rules. A future proportionate change in the composition of income before income taxes from foreign and domestic tax jurisdictions could impact our periodic effective tax rate.

Net equity in earnings (losses) of affiliates

Net equity in earnings (losses) of affiliates decreased $17 million to a loss of $6 million for the three months ended March 31, 2019, compared to earnings of $11 million for the three months ended March 31, 2018. This decrease was primarily due to decreased earnings at sPower driven by 2018 unrealized derivative gains and higher 2019 interest expense due to the timing of completed projects, the sale of Elsta in Q3 2018, and decreased earnings at Distributed Energy driven by the acquisition of certain of our non-controlling interests in late 2018.

Net income attributable to noncontrolling interests and redeemable stock of subsidiaries

Net income attributable to noncontrolling interests and redeemable stock of subsidiaries decreased $14 million, or 15%, to $79 million for the three months ended March 31, 2019, compared to $93 million for the three months ended March 31, 2018. This decrease was primarily due to:

• Lower earnings due to the sale of Masinloc in March 2018; and

• Lower earnings in Panama primarily due to lower hydrology and the outage at Changuinola as a result of the tunnel inspection. See Item 2.—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Trends and Uncertainties—Changuinola Tunnel Leak of this Form 10-Q for further information.

Net income attributable to The AES Corporation

Net income attributable to The AES Corporation decreased $530 million, or 77%, to $154 million for the three months ended March 31, 2019, compared to $684 million for the three months ended March 31, 2018. This decrease was primarily due to:

• Prior year gain on sale of Masinloc, net of tax; and

• Lower margins at our South America, MCAC and Eurasia SBUs.

These decreases were partially offset by:

• Prior year loss on extinguishment of debt at the Parent Company;

• Higher margins at our US and Utilities SBU; and

• Current period gains on insurance proceeds associated with the lightning incident at the Andres facility in 2018.

SBU Performance Analysis

Non-GAAP Measures

Adjusted Operating Margin, Adjusted PTC and Adjusted EPS are non-GAAP supplemental measures that are used by management and external users of our condensed consolidated financial statements such as investors, industry analysts and lenders.

28

Adjusted Operating Margin

We define Adjusted Operating Margin as Operating Margin, adjusted for the impact of NCI, excluding (a) unrealized gains or losses related to derivative transactions; (b) benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures; and (c) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. The allocation of HLBV earnings to noncontrolling interests is not adjusted out of Adjusted Operating Margin. See Review of Consolidated Results of Operations for the definition of Operating Margin.

The GAAP measure most comparable to Adjusted Operating Margin is Operating Margin. We believe that Adjusted Operating Margin better reflects the underlying business performance of the Company. Factors in this determination include the impact of NCI, where AES consolidates the results of a subsidiary that is not wholly owned by the Company, as well as the variability due to unrealized gains or losses related to derivative transactions and strategic decisions to dispose of or acquire business interests. Adjusted Operating Margin should not be construed as an alternative to Operating Margin, which is determined in accordance with GAAP.

Restructuring costs	—			3
Total Adjusted Operating Margin	$	430		$	502

_______________________

⁽¹⁾  The allocation of HLBV earnings to noncontrolling interests is not adjusted out of Adjusted Operating Margin.

Adjusted PTC

We define Adjusted PTC as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures; (d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities.

Adjusted PTC reflects the impact of NCI and excludes the items specified in the definition above. In addition to the revenue and cost of sales reflected in Operating Margin, Adjusted PTC includes the other components of our income statement, such as general and administrative expenses in the Corporate segment, as well as business development costs, interest expense and interest income, other expense and other income, realized foreign currency transaction gains and losses, and net equity in earnings of affiliates.

The GAAP measure most comparable to Adjusted PTC is income from continuing operations attributable to

29

The AES Corporation. We believe that Adjusted PTC better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company’s internal evaluation of the financial performance of its segments. Factors in this determination include the variability due to unrealized gains or losses related to derivative transactions or equity securities remeasurement, unrealized foreign currency gains or losses, losses due to impairments and strategic decisions to dispose of or acquire business interests, retire debt or implement restructuring initiatives, which affect results in a given period or periods. In addition, earnings before tax represents the business performance of the Company before the application of statutory income tax rates and tax adjustments, including the effects of tax planning, corresponding to the various jurisdictions in which the Company operates. Given its large number of businesses and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company’s results.

Adjusted PTC should not be construed as an alternative to income from continuing operations attributable to The AES Corporation, which is determined in accordance with GAAP.

Adjusted EPS

We define Adjusted EPS as diluted earnings per share from continuing operations excluding gains or losses of both consolidated entities and entities accounted for under the equity method due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures, and the tax impact from the repatriation of sales proceeds; (d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation; and (g) tax benefit or expense related to the enactment effects of 2017 U.S. tax law reform and related regulations and any subsequent period adjustments related to enactment effects.

The GAAP measure most comparable to Adjusted EPS is diluted earnings per share from continuing operations. We believe that Adjusted EPS better reflects the underlying business performance of the Company and is considered in the Company’s internal evaluation of financial performance. Factors in this determination include the variability due to unrealized gains or losses related to derivative transactions or equity securities remeasurement, unrealized foreign currency gains or losses, losses due to impairments and strategic decisions to

30

dispose of or acquire business interests, retire debt or implement restructuring activities, which affect results in a given period or periods.

Adjusted EPS should not be construed as an alternative to diluted earnings per share from continuing operations, which is determined in accordance with GAAP.

Key Trends and Uncertainties

During the remainder of 2019 and beyond, we expect to face the following challenges at certain of our businesses. Management expects that improved operating performance at certain businesses, growth from new businesses and global cost reduction initiatives may lessen or offset their impact. If these favorable effects do not occur, or if the challenges described below and elsewhere in this section impact us more significantly than we currently anticipate, or if volatile foreign currencies and commodities move more unfavorably, then these adverse factors (or other adverse factors unknown to us) may have a material impact on our operating margin, net income attributable to The AES Corporation, and cash flows. We continue to monitor our operations and address challenges as they arise. For the risk factors related to our business, see Item 1.—Business and Item 1A.—Risk Factors of our 2018 Form 10-K.

Macroeconomic and Political

During the past few years, some countries where our subsidiaries conduct business have experienced macroeconomic and political changes. In the event these trends continue, there could be an adverse impact on our businesses.

United States Tax Law Reform — In light of the significant changes to the U.S. tax system enacted in 2017, the U.S. Treasury Department and Internal Revenue Service have issued numerous regulations. While certain regulations are now final, there are many regulations that are proposed and still others anticipated to be issued in proposed form. The final version of any regulations may vary from the proposed form. When final, these regulations may materially impact our effective tax rate. Certain of the proposed regulations, when final, may have retroactive effect to January 1, 2018 or January 1, 2019. 

Puerto Rico — As discussed in Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Trends and Uncertainties of the 2018 Form 10-K, our subsidiaries in Puerto Rico have a long-term PPA with state-owned PREPA, which has been facing economic challenges that could result in a material adverse effect on our business in Puerto Rico.

AES Puerto Rico and AES Ilumina’s non-recourse debt of $311 million and $34 million, respectively, continue to be in default and are classified as current as of March 31, 2019 as a result of PREPA´s bankruptcy filing in July 2017. The Company is in compliance with its debt payment obligations as of March 31, 2019.

The Company's receivable balances in Puerto Rico as of March 31, 2019 totaled $70 million, of which $20 million was overdue. Despite the Title III protection, PREPA has been making substantially all of its payments to the generators in line with historical payment patterns.

On April 11, 2019, the Governor of Puerto Rico signed the Puerto Rico Energy Public Policy Act (“the Act”) into law. The Act established guidelines for grid efficiency and includes the elimination of coal as a source for electricity generation by January 1, 2028. The Act supports the accelerated deployment of renewables through the Renewable Portfolio Standard and the conversion of coal generating facilities to other fuel sources, with compliance targets of 40% by 2025, 60% by 2040, and 100% by 2050. AES Puerto Rico’s long-term PPA with PREPA expires November 31, 2027. We are considering alternatives allowed under the law and evaluating the impact of this change, which could have a material impact on the Company’s financial statements. Considering the information available as of the filing date, management believes the carrying amount of our assets in Puerto Rico of $607 million is recoverable as of March 31, 2019.

Argentina — On February 28, 2019, the Secretary of Energy in Argentina issued Resolution 1/2019 that modified the remuneration scheme for thermal generators as previously introduced by Resolution 19/2017. The entrance of renewable energy and efficient thermal generators in the market over the past few years supported the reduction of system costs and efficiency while fostering competition. Capacity prices for thermal generators will be subject to the actual dispatch of the generating facilities. Under Resolution 1/2019, the remuneration for energy is reduced by $1.6 per MWh for all thermal generation compared to Resolution 19/2017. For hydroelectric generation, there were no changes in capacity or energy prices. These measures are intended to help the government of Argentina reduce the subsidies and the financial deficit of the electric market.

United Kingdom — In June 2016, the UK held a referendum in which voters approved an exit from the EU, commonly referred to as “Brexit.” The UK parliament has rejected, on three occasions, proposed withdrawal agreements that the EU had supported. The UK was originally expected to exit the EU on March 29, 2019, which has been delayed to October 31, 2019. While the full impact of Brexit remains uncertain, these changes are not expected to have a material adverse effect on our operations and consolidated financial results.

33

Regulatory

In September 2018, DP&L received an order from PUCO establishing new base distribution rates for DP&L. Under the approved terms of the order, DP&L agreed to file an application with PUCO to refund customers eligible excess accumulated deferred income taxes associated with the TCJA and any related regulatory liability. DP&L filed this application on March 1, 2019 and proposed to return a total of $65 million to customers. The timing and final amount to be returned to customers is unknown at this time.

Foreign Exchange Rates

We operate in multiple countries and as such are subject to volatility in exchange rates at varying degrees at the subsidiary level and between our functional currency, the USD, and currencies of the countries in which we operate. In the first quarter of 2019, there was continued significant devaluation in the Argentine peso against the USD. Further material devaluation of the Argentine peso against the USD could have an impact on our full year 2019 results, largely in local tax expense. For additional information, refer to Item 3.—Quantitative and Qualitative Disclosures About Market Risk.

Andres

As discussed in Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Trends and Uncertainties of the 2018 Form 10-K, on September 3, 2018, lightning affected the Andres 319 MW combined cycle natural gas facility in the Dominican Republic (“the Plant”) resulting in significant damage to its steam turbine and generator. The Company has business interruption and property damage insurance coverage, subject to pre-defined deductibles, under its existing programs.

On September 25, 2018, the Plant restarted operations running the gas turbine in simple cycle at partial load of approximately 120 MW. Management estimates that the Plant will begin operating the gas turbine in simple cycle at full load of approximately 185 MW starting in the second quarter of 2019, and in combined cycle at full capacity by the fourth quarter of 2019. To mitigate the impact of the reduced capacity in the local energy market, the Company installed 120 MW of rental power (gas turbines) until the combined cycle facility is at full load. The rental units were fully operational beginning in December 2018.

Considering the information available as of the filing date, Management believes the carrying amount of our long-lived assets in Andres of $418 million is recoverable as of March 31, 2019.

Changuinola Tunnel Leak

As discussed in Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Trends and Uncertainties of the 2018 Form 10-K, increased water levels were noted in a creek near the Changuinola power plant, a 223 MW hydroelectric power facility in Panama. After the completion of an assessment, the Company has confirmed loss of water in specific sections of the tunnel. To ensure the long-term performance of the facility, the affected units of the plant have been taken out of service until final inspection and replacement of the damaged sections of tunnel is complete. This process began in January 2019 and may take up to 10 months to complete. The Company has notified its insurers of a potential claim and has asserted claims against its construction contractor; however, there can be no assurance of collection and the Company continues to monitor the situation. The Company has not identified any indicators of impairment and believes the carrying value of the long-lived asset group of $933 million is recoverable as of March 31, 2019.

Impairments

Events or changes in circumstances that may necessitate recoverability tests and potential impairments of long-lived assets or goodwill may include, but are not limited to, adverse changes in the regulatory environment, unfavorable changes in power prices or fuel costs, increased competition due to additional capacity in the grid, technological advancements, declining trends in demand, or an expectation it is more likely than not the asset will be disposed of before the end of its estimated useful life.

Environmental

The Company is subject to numerous environmental laws and regulations in the jurisdictions in which it operates. The Company faces certain risks and uncertainties related to these environmental laws and regulations, including existing and potential GHG legislation or regulations, and actual or potential laws and regulations pertaining to water discharges, waste management (including disposal of coal combustion residuals) and certain air emissions, such as SO₂, NO_x, particulate matter, mercury and other hazardous air pollutants. Such risks and uncertainties could result in increased capital expenditures or other compliance costs which could have a material adverse effect on certain of our U.S. or international subsidiaries and our consolidated results of operations. For

34

further information about these risks, see Item 1A.—Risk Factors—Our operations are subject to significant government regulation and our business and results of operations could be adversely affected by changes in the law or regulatory schemes; Several of our businesses are subject to potentially significant remediation expenses, enforcement initiatives, private party lawsuits and reputational risk associated with CCR; Our businesses are subject to stringent environmental laws, rules and regulations; and Concerns about GHG emissions and the potential risks associated with climate change have led to increased regulation and other actions that could impact our businesses included in the 2018 Form 10-K.

Capital Resources and Liquidity

Overview — As of March 31, 2019, the Company had unrestricted cash and cash equivalents of $1.4 billion, of which $34 million was held at the Parent Company and qualified holding companies. The Company also had $378 million in short-term investments, held primarily at subsidiaries. In addition, we had restricted cash and debt service reserves of $949 million. The Company also had non-recourse and recourse aggregate principal amounts of debt outstanding of $15.8 billion and $3.9 billion, respectively. Of the approximately $1.3 billion of our current non-recourse debt, $920 million was presented as such because it is due in the next twelve months and $345 million relates to debt considered in default due to covenant violations. None of the defaults are payment defaults, but are instead technical defaults triggered by failure to comply with other covenants or other conditions contained in the non-recourse debt documents due to the bankruptcy of the offtaker.

We expect current maturities of non-recourse debt to be repaid from net cash provided by operating activities of the subsidiary to which the debt relates, through opportunistic refinancing activity, or some combination thereof. We have $5 million of recourse debt which matures within the next twelve months. From time to time, we may elect to repurchase our outstanding debt through cash purchases, privately negotiated transactions or otherwise when management believes that such securities are attractively priced. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements and other factors. The amounts involved in any such repurchases may be material.

We rely mainly on long-term debt obligations to fund our construction activities. We have, to the extent available at acceptable terms, utilized non-recourse debt to fund a significant portion of the capital expenditures and investments required to construct and acquire our electric power plants, distribution companies and related assets. Our non-recourse financing is designed to limit cross-default risk to the Parent Company or other subsidiaries and affiliates. Our non-recourse long-term debt is a combination of fixed and variable interest rate instruments. Debt is typically denominated in the currency that matches the currency of the revenue expected to be generated from the benefiting project, thereby reducing currency risk. In certain cases, the currency is matched through the use of derivative instruments. The majority of our non-recourse debt is funded by international commercial banks, with debt capacity supplemented by multilaterals and local regional banks.

Given our long-term debt obligations, the Company is subject to interest rate risk on debt balances that accrue interest at variable rates. When possible, the Company will borrow funds at fixed interest rates or hedge its variable rate debt to fix its interest costs on such obligations. In addition, the Company has historically tried to maintain at least 70% of its consolidated long-term obligations at fixed interest rates, including fixing the interest rate through the use of interest rate swaps. These efforts apply to the notional amount of the swaps compared to the amount of related underlying debt. Presently, the Parent Company’s only material unhedged exposure to variable interest rate debt relates to indebtedness under its $365 million outstanding secured term loan due 2022 and drawings of $245 million under its senior secured credit facility. On a consolidated basis, of the Company’s $20.1 billion of total gross debt outstanding as of March 31, 2019, approximately $2.3 billion bore interest at variable rates that were not subject to a derivative instrument which fixed the interest rate. Brazil holds $1 billion of our floating rate non-recourse exposure as we have no ability to fix local debt interest rates efficiently.

In addition to utilizing non-recourse debt at a subsidiary level when available, the Parent Company provides a portion, or in certain instances all, of the remaining long-term financing or credit required to fund development, construction or acquisition of a particular project. These investments have generally taken the form of equity investments or intercompany loans, which are subordinated to the project’s non-recourse loans. We generally obtain the funds for these investments from our cash flows from operations, proceeds from the sales of assets and/or the proceeds from our issuances of debt, common stock and other securities. Similarly, in certain of our businesses, the Parent Company may provide financial guarantees or other credit support for the benefit of counterparties who have entered into contracts for the purchase or sale of electricity, equipment, or other services with our subsidiaries or lenders. In such circumstances, if a business defaults on its payment or supply obligation, the Parent Company will be responsible for the business’ obligations up to the amount provided for in the relevant guarantee or other credit support. At March 31, 2019, the Parent Company had provided outstanding financial and

35

performance-related guarantees or other credit support commitments to or for the benefit of our businesses, which were limited by the terms of the agreements, of approximately $660 million in aggregate (excluding those collateralized by letters of credit and other obligations discussed below).

As a result of the Parent Company’s below investment grade rating, counterparties may be unwilling to accept our general unsecured commitments to provide credit support. Accordingly, with respect to both new and existing commitments, the Parent Company may be required to provide some other form of assurance, such as a letter of credit, to backstop or replace our credit support. The Parent Company may not be able to provide adequate assurances to such counterparties. To the extent we are required and able to provide letters of credit or other collateral to such counterparties, this will reduce the amount of credit available to us to meet our other liquidity needs. At March 31, 2019, we had $368 million in letters of credit outstanding provided under our unsecured credit facility and $80 million in letters of credit outstanding provided under our senior secured credit facility. These letters of credit operate to guarantee performance relating to certain project development and construction activities and business operations. During the quarter ended March 31, 2019, the Company paid letter of credit fees ranging from 1% to 3% per annum on the outstanding amounts.

We expect to continue to seek, where possible, non-recourse debt financing in connection with the assets or businesses that we or our affiliates may develop, construct or acquire. However, depending on local and global market conditions and the unique characteristics of individual businesses, non-recourse debt may not be available on economically attractive terms or at all. If we decide not to provide any additional funding or credit support to a subsidiary project that is under construction or has near-term debt payment obligations and that subsidiary is unable to obtain additional non-recourse debt, such subsidiary may become insolvent, and we may lose our investment in that subsidiary. Additionally, if any of our subsidiaries lose a significant customer, the subsidiary may need to withdraw from a project or restructure the non-recourse debt financing. If we or the subsidiary choose not to proceed with a project or are unable to successfully complete a restructuring of the non-recourse debt, we may lose our investment in that subsidiary.

Many of our subsidiaries depend on timely and continued access to capital markets to manage their liquidity needs. The inability to raise capital on favorable terms, to refinance existing indebtedness or to fund operations and other commitments during times of political or economic uncertainty may have material adverse effects on the financial condition and results of operations of those subsidiaries. In addition, changes in the timing of tariff increases or delays in the regulatory determinations under the relevant concessions could affect the cash flows and results of operations of our businesses.

Long-Term Receivables — As of March 31, 2019, the Company had approximately $110 million of accounts receivable classified as Noncurrent assets—other. These noncurrent receivables mostly consist of accounts receivable in Argentina that, pursuant to amended agreements or government resolutions, have collection periods that extend beyond March 31, 2020, or one year from the latest balance sheet date. The majority of Argentinian receivables have been converted into long-term financing for the construction of power plants. See Note 6—Financing Receivables in Item 1.—Financial Statements of this Form 10-Q and Item 1.—Business—South America SBU—Argentina—Regulatory Framework included in our 2018 Form 10-K for further information.

As of March 31, 2019, the Company had approximately $1.4 billion of loans receivable primarily related to a facility constructed under a build, operate, and transfer contract in Vietnam. This loan receivable represents contract consideration related to the construction of the facility, which was substantially completed in 2015, and will be collected over the 25 year term of the plant’s PPA. See Note 14—Revenue in Item 1.—Financial Statements of this Form 10-Q for further information.

Operating Activities

Net cash provided by operating activities increased by $175 million for the three months ended March 31, 2019, compared to the three months ended March 31, 2018.

Operating Cash Flows

(in millions)

⁽¹⁾  The change in adjusted net income is defined as the variance in net income, net of the total adjustments to net income as shown on the Condensed Consolidated Statements of Cash Flows in Item 1.—Financial Statements of this Form 10-Q.

⁽²⁾  The change in working capital is defined as the variance in total changes in operating assets and liabilities as shown on the Condensed Consolidated Statements of Cash Flows in Item 1.—Financial Statements of this Form 10-Q.

Amounts included in the chart above include the results of discontinued operations, where applicable.

37

• Adjusted net income was essentially flat compared to the prior year.

• Working capital requirements decreased by $181 million, primarily due to lower payments to suppliers at Gener, higher collections of overdue receivables from distribution companies in the Dominican Republic, collections of business interruption insurance proceeds at Andres due to the steam turbine damage claim from 2018, and lower interest payments at the Parent Company. These impacts were partially offset by the timing of VAT payments at Gener.

Investing Activities

Net cash provided by investing activities decreased by $1.1 billion for the three months ended March 31, 2019, compared to the three months ended March 31, 2018.

Investing Cash Flows

(in millions)

• Proceeds from dispositions decreased by $1.2 billion, primarily due to the sales of Masinloc and the DPL Peaker assets in 2018.

• Cash used for short-term investing activities decreased by $126 million, primarily due to the prior year purchases of non-convertible debentures at Tietê to provide project financing for the construction of the Bauru Solar Complex.

• Capital expenditures increased by $9 million, discussed further below.

Capital Expenditures

(in millions)

38

• Growth expenditures decreased by $36 million, primarily due to timing of payments for the Southland re-powering project, completion of the Colon combined cycle facility in 2018, and the sale of Masinloc in 2018. These impacts were partially offset by higher spending at Alto Maipo as a result of the Strabag agreement executed in the second quarter of 2018 for construction financing.

• Maintenance expenditures increased by $49 million, primarily at Andres as a result of the steam turbine lightning damage, and at IPALCO due to the timing of payments for outage related expenses.

Financing Activities

Net cash provided by financing activities increased $1 billion for the three months ended March 31, 2019, compared to the three months ended March 31, 2018.

Financing Cash Flows

(in millions)

See Note 8—Debt in Item 1—Financial Statements of this Form 10-Q for more information regarding significant debt transactions.

• The $773 million impact from recourse debt activity is primarily due to the accelerated net repayments of Parent Company debt in the prior year.

• The $195 million impact from parent revolver transactions is primarily due to higher net borrowings in 2019 for general corporate cash management activities.

• The $191 million impact from non-recourse debt transactions is primarily due to net issuances at Gener and lower repayments at DPL, which were partially offset by net issuances at Tietê in the prior year.

• The $63 million impact from non-recourse revolver transactions is primarily due to repayments at Gener.

Parent Company Liquidity

The following discussion is included as a useful measure of the liquidity available to The AES Corporation, or the Parent Company, given the non-recourse nature of most of our indebtedness. Parent Company Liquidity as outlined below is a non-GAAP measure and should not be construed as an alternative to cash and cash equivalents, which is determined in accordance with GAAP. Parent Company Liquidity may differ from similarly titled measures used by other companies. The principal sources of liquidity at the Parent Company level are dividends and other distributions from our subsidiaries, including refinancing proceeds, proceeds from debt and equity financings at the Parent Company level, including availability under our credit facility, and proceeds from asset sales. Cash requirements at the Parent Company level are primarily to fund interest and principal repayments of debt, construction commitments, other equity commitments, common stock repurchases, acquisitions, taxes, Parent Company overhead and development costs, and dividends on common stock.

The Company defines Parent Company Liquidity as cash available to the Parent Company plus available borrowings under existing credit facility plus cash at qualified holding companies. The cash held at qualified holding companies represents cash sent to subsidiaries of the Company domiciled outside of the U.S. Such subsidiaries have no contractual restrictions on their ability to send cash to the Parent Company. Parent Company Liquidity is reconciled to its most directly comparable GAAP financial measure, cash and cash equivalents, at the periods indicated as follows (in millions):

39

	March 31, 2019			December 31, 2018
Consolidated cash and cash equivalents	$	1,426		$	1,166
Less: Cash and cash equivalents at subsidiaries	(1,392		)	(1,142		)
Parent Company and qualified holding companies’ cash and cash equivalents	34			24
Commitments under Parent Company credit facility	1,100			1,100
Less: Letters of credit under the credit facility	(80		)	(78		)
Less: Borrowings under the credit facility	(245		)	—
Borrowings available under Parent Company credit facility	775			1,022
Total Parent Company Liquidity	$	809		$	1,046

The Company utilizes its Parent Company credit facility for short term cash needs to bridge timing of distributions from its subsidiaries throughout the year. The Company is expecting that the Parent Company credit facilities’ borrowings will be repaid by the end of year, but can make no assurances this will occur as currently forecasted.

The Parent Company paid dividends of $0.1365 per share to its common stockholders during the first quarter of 2019 for dividends declared in December 2018. While we intend to continue payment of dividends, and believe we will have sufficient liquidity to do so, we can provide no assurance that we will continue to pay dividends, or if continued, the amount of such dividends.

Recourse Debt

Our total recourse debt was $3.9 billion and $3.7 billion as of March 31, 2019 and December 31, 2018, respectively. See Note 8—Debt in Item 1.—Financial Statements of this Form 10-Q and Note 10—Debt in Item 8.—Financial Statements and Supplementary Data of our 2018 Form 10-K for additional detail.

While we believe that our sources of liquidity will be adequate to meet our needs for the foreseeable future, this belief is based on a number of material assumptions, including, without limitation, assumptions about our ability to access the capital markets, the operating and financial performance of our subsidiaries, currency exchange rates, power market pool prices, and the ability of our subsidiaries to pay dividends. In addition, our subsidiaries’ ability to declare and pay cash dividends to us (at the Parent Company level) is subject to certain limitations contained in loans, governmental provisions and other agreements. We can provide no assurance that these sources will be available when needed or that the actual cash requirements will not be greater than anticipated. We have met our interim needs for shorter-term and working capital financing at the Parent Company level with our senior secured credit facility. See Item 1A.—Risk Factors—The AES Corporation is a holding company and its ability to make payments on its outstanding indebtedness, including its public debt securities, is dependent upon the receipt of funds from its subsidiaries by way of dividends, fees, interest, loans or otherwise of the Company’s 2018 Form 10-K for additional information.

Various debt instruments at the Parent Company level, including our senior secured credit facility, contain certain restrictive covenants. The covenants provide for, among other items, limitations on other indebtedness, liens, investments and guarantees; limitations on dividends, stock repurchases and other equity transactions; restrictions and limitations on mergers and acquisitions, sales of assets, leases, transactions with affiliates and off-balance sheet and derivative arrangements; maintenance of certain financial ratios; and financial and other reporting requirements. As of March 31, 2019, we were in compliance with these covenants at the Parent Company level.

Non-Recourse Debt

While the lenders under our non-recourse debt financings generally do not have direct recourse to the Parent Company, defaults thereunder can still have important consequences for our results of operations and liquidity, including, without limitation:

• reducing our cash flows as the subsidiary will typically be prohibited from distributing cash to the Parent Company during the time period of any default;

• triggering our obligation to make payments under any financial guarantee, letter of credit or other credit support we have provided to or on behalf of such subsidiary;

• causing us to record a loss in the event the lender forecloses on the assets; and

• triggering defaults in our outstanding debt at the Parent Company.

For example, our senior secured credit facility and outstanding debt securities at the Parent Company include events of default for certain bankruptcy-related events involving material subsidiaries. In addition, our revolving credit agreement at the Parent Company includes events of default related to payment defaults and accelerations of outstanding debt of material subsidiaries.

40

Some of our subsidiaries are currently in default with respect to all or a portion of their outstanding indebtedness. The total non-recourse debt classified as current in the accompanying Condensed Consolidated Balance Sheets amounts to $1.3 billion. The portion of current debt related to such defaults was $345 million at March 31, 2019, all of which was non-recourse debt related to two subsidiaries — AES Puerto Rico and AES Ilumina. See Note 8—Debt in Item 1.—Financial Statements of this Form 10-Q for additional detail.

None of the subsidiaries that are currently in default are subsidiaries that met the applicable definition of materiality under the Parent Company’s debt agreements as of March 31, 2019, in order for such defaults to trigger an event of default or permit acceleration under the Parent Company’s indebtedness. However, as a result of additional dispositions of assets, other significant reductions in asset carrying values or other matters in the future that may impact our financial position and results of operations or the financial position of the individual subsidiary, it is possible that one or more of these subsidiaries could fall within the definition of a “material subsidiary” and thereby trigger an event of default and possible acceleration of the indebtedness under the Parent Company’s outstanding debt securities. A material subsidiary is defined in the Parent Company’s senior secured credit facility as any business that contributed 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently ended fiscal quarters. As of March 31, 2019, none of the defaults listed above individually or in the aggregate results in or is at risk of triggering a cross-default under the recourse debt of the Parent Company.

Critical Accounting Policies and Estimates

The condensed consolidated financial statements of AES are prepared in conformity with U.S. GAAP, which requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the periods presented.

Leases — Under the accounting standard for leases, the Company recognizes operating and finance right-of-use assets and lease liabilities on the Consolidated Balance Sheets for most leases with an initial term of greater than 12 months. Lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. Our subsidiaries’ incremental borrowing rates are used in determining the present value of lease payments when the implicit rate is not readily determinable. Certain adjustments to the right-of-use asset may be required for items such as prepayments, lease incentives or initial direct costs. For further information regarding the nature of our leases and our critical accounting policies effecting leases, see Note 10—Leases included in Item 1.—Financial Statements of this Form 10-Q.

The Company’s significant accounting policies are described in Note 1—General and Summary of Significant Accounting Policies of our 2018 Form 10-K. The Company’s critical accounting estimates are described in Item 7.—Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2018 Form 10-K. An accounting estimate is considered critical if the estimate requires management to make an assumption about matters that were highly uncertain at the time the estimate was made, different estimates reasonably could have been used, or if changes in the estimate that would have a material impact on the Company’s financial condition or results of operations are reasonably likely to occur from period to period. Management believes that the accounting estimates employed are appropriate and resulting balances are reasonable; however, actual results could differ from the original estimates, requiring adjustments to these balances in future periods. The Company has reviewed and determined that these remain as critical accounting policies as of and for the three months ended March 31, 2019.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Overview Regarding Market Risks — Our businesses are exposed to and proactively manage market risk. Our primary market risk exposure is to the price of commodities, particularly electricity, oil, natural gas, coal and environmental credits. In addition, our businesses are exposed to lower electricity prices due to increased competition, including from renewable sources such as wind and solar, as a result of lower costs of entry and lower variable costs. We operate in multiple countries and as such, are subject to volatility in exchange rates at varying degrees at the subsidiary level and between our functional currency, the U.S. dollar, and currencies of the countries in which we operate. We are also exposed to interest rate fluctuations due to our issuance of debt and related financial instruments.

The disclosures presented in this Item 3 are based upon a number of assumptions; actual effects may differ. The safe harbor provided in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 shall apply to the disclosures contained in this Item 3. For further information regarding market risk, see Item 1A.—Risk Factors, Our financial position and results of operations may fluctuate significantly due to fluctuations in currency exchange rates experienced at our foreign operations; Wholesale power prices are declining in many markets, and this could have a material adverse effect on our operations and opportunities for

41

future growth, and We may not be adequately hedged against our exposure to changes in commodity prices or interest rates of the 2018 Form 10-K.

Commodity Price Risk — Although we prefer to hedge our exposure to the impact of market fluctuations in the price of electricity, fuels and environmental credits, some of our generation businesses operate under short-term sales or under contract sales that leave an unhedged exposure on some of our capacity or through imperfect fuel pass-throughs. These businesses subject our operational results to the volatility of prices for electricity, fuels and environmental credits in competitive markets. We employ risk management strategies to hedge our financial performance against the effects of fluctuations in energy commodity prices. The implementation of these strategies can involve the use of physical and financial commodity contracts, futures, swaps and options.

The portion of our sales and purchases that are not subject to such agreements or contracted businesses where indexation is not perfectly matched to business drivers will be exposed to commodity price risk. When hedging the output of our generation assets, we utilize contract sales that lock in the spread per MWh between variable costs and the price at which the electricity can be sold.

AES businesses will see changes in variable margin performance as global commodity prices shift. For 2019, we project pre-tax earnings exposure on a 10% move in commodity prices would be approximately $5 million for U.S. power, $(5) million for natural gas, $(5) million for oil, and $(5) million for coal. Our estimates exclude correlation of oil with coal or natural gas. For example, a decline in oil or natural gas prices can be accompanied by a decline in coal price if commodity prices are correlated. In aggregate, the Company’s downside exposure occurs with lower power, higher oil, higher natural gas, and higher coal prices. Exposures at individual businesses will change as new contracts or financial hedges are executed, and our sensitivity to changes in commodity prices generally increases in later years with reduced hedge levels at some of our businesses.

Commodity prices affect our businesses differently depending on the local market characteristics and risk management strategies. Spot power prices, contract indexation provisions and generation costs can be directly or indirectly affected by movements in the price of natural gas, oil and coal. We have some natural offsets across our businesses such that low commodity prices may benefit certain businesses and be a cost to others. Exposures are not perfectly linear or symmetric. The sensitivities are affected by a number of local or indirect market factors. Examples of these factors include hydrology, local energy market supply/demand balances, regional fuel supply issues, regional competition, bidding strategies and regulatory interventions such as price caps. Operational flexibility changes the shape of our sensitivities. For instance, certain power plants may limit downside exposure by reducing dispatch in low market environments. Volume variation also affects our commodity exposure. The volume sold under contracts or retail concessions can vary based on weather and economic conditions resulting in a higher or lower volume of sales in spot markets. Thermal unit availability and hydrology can affect the generation output available for sale and can affect the marginal unit setting power prices.

In the US and Utilities SBU, the generation businesses are largely contracted, but may have residual risk to the extent contracts are not perfectly indexed to the business drivers. At Southland, our primary contracts are in capacity and it has seen incremental location value in energy revenues; this will continue until 2020 when our Southland repowering project and contract begin.

In the South America SBU, our business in Chile owns assets in the central and northern regions of the country and has a portfolio of contract sales in both. In the central region, the contract sales generally cover the efficient generation from our coal-fired and hydroelectric assets. Any residual spot price risk will primarily be driven by the amount of hydrological inflows. In the case of low hydroelectric generation, spot price exposure is capped by the ability to dispatch our natural gas/diesel assets, the price of which depends on fuel pricing at the time required. There is a small amount of coal generation in the northern region that is not covered by the portfolio of contract sales and therefore subject to spot price risk. In both regions, under normal hydrology conditions, coal-firing generation sets the price. However, when there are spikes in price due to lower hydrology and higher demand, gas or oil-linked fuels generally set power prices. In Colombia, we operate under a short-term sales strategy and have commodity exposure to unhedged volumes. Because we own hydroelectric assets there, contracts are not indexed to fuel. Additionally, in Brazil, the hydroelectric generating facility is covered by contract sales. Under normal hydrological volatility, spot price risk is mitigated through a regulated sharing mechanism across all hydroelectric generators in the country. Under drier conditions, the sharing mechanism may not be sufficient to cover the business' contract position, and therefore it may have to purchase power at spot prices driven by the cost of thermal generation.

In the MCAC SBU, our businesses have commodity exposure on unhedged volumes. Panama is highly contracted under a portfolio of fixed volume contract sales. To the extent hydrological inflows are greater than or less than the contract sales volume, the business will be sensitive to changes in spot power prices which may be

42

driven by oil prices in some time periods. In Dominican Republic, we own natural gas-fired assets contracted under a portfolio of contract sales and a coal-fired asset contracted with a single contract, and both contract and spot prices may move with commodity prices. Additionally, the contract levels do not always match our generation availability and our assets may be sellers of spot prices in excess of contract levels or a net buyer in the spot market to satisfy contract obligations.

In the Eurasia SBU, our Mong Duong business has minimal exposure to commodity price risk as it has no merchant exposure and fuel is subject to a pass-through mechanism.

Foreign Exchange Rate Risk — In the normal course of business, we are exposed to foreign currency risk and other foreign operations risks that arise from investments in foreign subsidiaries and affiliates. A key component of these risks stems from the fact that some of our foreign subsidiaries and affiliates utilize currencies other than our consolidated reporting currency, the USD. Additionally, certain of our foreign subsidiaries and affiliates have entered into monetary obligations in USD or currencies other than their own functional currencies. Certain of our foreign subsidiaries calculate and pay taxes in currencies other than their own functional currency. We have varying degrees of exposure to changes in the exchange rate between the USD and the following currencies: Argentine peso, British pound, Brazilian real, Chilean peso, Colombian peso, Dominican peso, Euro, Indian rupee, and Mexican peso. These subsidiaries and affiliates have attempted to limit potential foreign exchange exposure by entering into revenue contracts that adjust to changes in foreign exchange rates. We also use foreign currency forwards, swaps and options, where possible, to manage our risk related to certain foreign currency fluctuations.

AES enters into foreign currency hedges to protect economic value of the business and minimize the impact of foreign exchange rate fluctuations to AES’ portfolio. While protecting cash flows, the hedging strategy is also designed to reduce forward looking earnings foreign exchange volatility. Due to variation of timing and amount between cash distribution and earnings exposure, the hedge impact may not fully cover the earnings exposure on a realized basis which could result in greater volatility in earnings. The largest foreign exchange risks over a 9-month forward-looking period of 2019 stem from the following currencies: Argentine peso, Brazilian real, Colombian peso, Euro, British pound, and Indian Rupee. As of March 31, 2019, assuming a 10% USD appreciation, cash distributions attributable to foreign subsidiaries exposed to movement in the exchange rate of the British pound, Euro, Argentine peso, Colombian peso, Brazilian real, and Indian Rupee each are projected to be impacted by less than $5 million. These numbers have been produced by applying a one-time 10% USD appreciation to forecasted exposed cash distributions for 2019 coming from the respective subsidiaries exposed to the currencies listed above, net of the impact of outstanding hedges and holding all other variables constant. The numbers presented above are net of any transactional gains/losses. These sensitivities may change in the future as new hedges are executed or existing hedges are unwound. Additionally, updates to the forecasted cash distributions exposed to foreign exchange risk may result in further modification. The sensitivities presented do not capture the impacts of any administrative market restrictions or currency inconvertibility.

Interest Rate Risks — We are exposed to risk resulting from changes in interest rates as a result of our issuance of variable and fixed-rate debt, as well as interest rate swap, cap, floor and option agreements.

Decisions on the fixed-floating debt mix are made to be consistent with the risk factors faced by individual businesses or plants. Depending on whether a plant’s capacity payments or revenue stream is fixed or varies with inflation, we partially hedge against interest rate fluctuations by arranging fixed-rate or variable-rate financing. In certain cases, particularly for non-recourse financing, we execute interest rate swap, cap and floor agreements to effectively fix or limit the interest rate exposure on the underlying financing. Most of our interest rate risk is related to non-recourse financings at our businesses.

As of March 31, 2019, the portfolio’s pre-tax earnings exposure for 2019 to a one-time 100-basis-point increase in interest rates for our Argentine peso, Brazilian real, Chilean peso, Colombian peso, Euro, and USD denominated debt would be approximately $15 million on interest expense for the debt denominated in these currencies. These amounts do not take into account the historical correlation between these interest rates.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures — The Company, under the supervision and with the participation of its management, including the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of its “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were effective as of March 31, 2019, to ensure that information required to be disclosed by the Company in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and include controls and

43

procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Controls over Financial Reporting — There were no changes that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The Company has accrued for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company believes, based upon information it currently possesses and taking into account established reserves for estimated liabilities and its insurance coverage, that the ultimate outcome of these proceedings and actions is unlikely to have a material adverse effect on the Company's condensed consolidated financial statements. It is reasonably possible, however, that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material, but cannot be estimated as of March 31, 2019.

In December 2001, Grid Corporation of Odisha (“GRIDCO”) served a notice to arbitrate pursuant to the Indian Arbitration and Conciliation Act of 1996 on the Company, AES Orissa Distribution Private Limited (“AES ODPL”), and Jyoti Structures (“Jyoti”) pursuant to the terms of the shareholders agreement between GRIDCO, the Company, AES ODPL, Jyoti and the Central Electricity Supply Company of Orissa Ltd. (“CESCO”), an affiliate of the Company. In the arbitration, GRIDCO asserted that a comfort letter issued by the Company in connection with the Company's indirect investment in CESCO obligates the Company to provide additional financial support to cover all of CESCO's financial obligations to GRIDCO. GRIDCO appeared to be seeking approximately $189 million in damages, plus undisclosed penalties and interest, but a detailed alleged damage analysis was not filed by GRIDCO. The Company counterclaimed against GRIDCO for damages. In June 2007, a 2-to-1 majority of the arbitral tribunal rendered its award rejecting GRIDCO's claims and holding that none of the respondents, the Company, AES ODPL, or Jyoti, had any liability to GRIDCO. The respondents' counterclaims were also rejected. A majority of the tribunal later awarded the respondents, including the Company, some of their costs relating to the arbitration. GRIDCO filed challenges of the tribunal's awards with the local Indian court. GRIDCO's challenge of the costs award has been dismissed by the court, but its challenge of the liability award remains pending. A hearing on the liability award has not taken place to date. The Company believes that it has meritorious defenses to the claims asserted against it and will defend itself vigorously in these proceedings; however, there can be no assurances that it will be successful in its efforts.

Pursuant to their environmental audit, AES Sul and AES Florestal discovered 200 barrels of solid creosote waste and other contaminants at a pole factory that AES Florestal had been operating. The conclusion of the audit was that a prior operator of the pole factory, Companhia Estadual de Energia (“CEEE”), had been using those contaminants to treat the poles that were manufactured at the factory. On their initiative, AES Sul and AES Florestal communicated with Brazilian authorities and CEEE about the adoption of containment and remediation measures. In March 2008, the State Attorney of the state of Rio Grande do Sul, Brazil filed a public civil action against AES Sul, AES Florestal and CEEE seeking an order requiring the companies to mitigate the contaminated area located on the grounds of the pole factory and an indemnity payment of approximately R$6 million ($2 million). In October 2011, the State Attorney filed a request for an injunction ordering the defendant companies to contain and remove the contamination immediately. The court granted injunctive relief on October 18, 2011, but determined that only CEEE was required to perform the removal work. In May 2012, CEEE began the removal work in compliance with the injunction. The case is now awaiting judgment. The removal costs are estimated to be approximately R$29 million ($8 million), and there could be additional remediation costs which cannot be estimated at this time. In June 2016 the Company sold AES Sul to CPFL Energia S.A. and as part of the sale, AES Guaiba, a holding company of AES Sul, retained the potential liability relating to this matter. The Company believes that there are meritorious defenses to the claims asserted against it and will defend itself vigorously in these proceedings; however, there can be no assurances that it will be successful in its efforts.

In January 2012, the Brazil Federal Tax Authority issued an assessment alleging that AES Tietê had paid PIS and COFINS taxes from 2007 to 2010 at a lower rate than the tax authority believed was applicable. AES Tietê challenged the assessment on the grounds that the tax rate was set in the applicable legislation. In April 2013, the FIAC determined that AES Tietê should have calculated the taxes at the higher rate and that AES Tietê was liable for unpaid taxes, interest, and penalties totaling approximately R$1.21 billion ($311 million) as estimated by AES Tietê. AES Tietê appealed to the SIAC. In January 2015, the Second Instance Administrative Court (“SIAC”) issued a decision in AES Tietê's favor, finding that AES Tietê was not liable for unpaid taxes. The public prosecutor subsequently filed an appeal, which was denied as untimely. The Tax Authority thereafter filed a motion for clarification of the SIAC's decision, which was denied in September 2016. The Tax Authority later filed a special appeal (“Special Appeal”), which was rejected as untimely in October 2016. The Tax Authority thereafter filed an interlocutory appeal with the Superior Administrative Court (“SAC”). In March 2017, the President of the SAC determined that the SAC would analyze the Special Appeal. AES Tietê challenged the Special Appeal. In May 2018, the SAC rejected the Special Appeal on the merits. In August 2018, the Tax Authority filed a motion for clarification.

45

In February 2019, the SAC rejected the motion. AES Tietê believes it has meritorious defenses to the claim and will defend itself vigorously in these proceedings; however, there can be no assurances that it will be successful in its efforts.

In January 2015, DPL received NOVs from the EPA alleging violations of opacity at Stuart and Killen Stations, and in October 2015, IPL received a similar NOV alleging violations at Petersburg Station. In February 2017, the EPA issued a second NOV for DPL Stuart Station, alleging violations of opacity in 2016. Moreover, in February 2016, IPL received an NOV from the EPA alleging violations of NSR and other CAA regulations, the Indiana SIP, and the Title V operating permit at Petersburg Station. It is too early to determine whether the NOVs could have a material impact on our business, financial condition or results of our operations. IPL 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 in this regard.

In September 2015, AES Southland Development, LLC and AES Redondo Beach, LLC filed a lawsuit against the California Coastal Commission (the “CCC”) over the CCC's determination that the site of AES Redondo Beach included approximately 5.93 acres of CCC-jurisdictional wetlands. The CCC has asserted that AES Redondo Beach has improperly installed and operated water pumps affecting the alleged wetlands in violation of the California Coastal Act and Redondo Beach Local Coastal Program and has ordered AES Redondo Beach to restore the site. Additional potential outcomes of the CCC determination could include an order requiring AES Redondo Beach to fund a wetland mitigation project and/or pay fines or penalties. AES Redondo Beach believes that it has meritorious arguments and intends to vigorously prosecute such lawsuit, but there can be no assurances that it will be successful.

In October 2015, Ganadera Guerra, S.A. (“GG”) and Constructora Tymsa, S.A. (“CT”) filed separate lawsuits against AES Panama in the local courts of Panama. The claimants allege that AES Panama profited from a hydropower facility (La Estrella) being partially located on land owned initially by GG and currently by CT, and that AES Panama must pay compensation for its use of the land. The damages sought from AES Panama are approximately $685 million (GG) and $100 million (CT). In October 2016, the court dismissed GG's claim because of GG's failure to comply with a court order requiring GG to disclose certain information. GG has refiled its lawsuit. Also, there are ongoing administrative proceedings concerning whether AES Panama is entitled to acquire an easement over the land and whether AES Panama can continue to occupy the land. AES Panama believes it has meritorious defenses and claims and will assert them vigorously; however, there can be no assurances that it will be successful in its efforts.

In January 2017, the Superintendencia del Medio Ambiente (“SMA”) issued a Formulation of Charges asserting that Alto Maipo is in violation of certain conditions of the Environmental Approval Resolution (“RCA”) governing the construction of Alto Maipo’s hydropower project, for, among other things, operating vehicles at unauthorized times and failing to mitigate the impact of water infiltration during tunnel construction (“Infiltration Water”). In February 2017, Alto Maipo submitted a compliance plan (“Compliance Plan”) to the SMA which, if approved by the agency, would resolve the matter without materially impacting construction of the project. Thereafter, the SMA made three separate requests for information about the Compliance Plan, to which Alto Maipo duly responded. In April 2018, the SMA approved the Compliance Plan (“April 2018 Approval”). Among other things, the Compliance Plan as approved by the SMA requires Alto Maipo to obtain from the Environmental Evaluation Service (“SEA”) an acceptable interpretation of the RCA’s provisions concerning the authorized times to operate certain vehicles. In addition, Alto Maipo must obtain the SEA’s approval concerning the control, discharge, and treatment of Infiltration Water. Alto Maipo continues to seek the relevant final approvals from the SEA. Furthermore, in May 2018, three lawsuits were filed with the Environmental Court of Santiago (“ECS”) challenging the April 2018 Approval. Alto Maipo does not believe that there are grounds to challenge the April 2018 Approval. The ECS has not decided the lawsuits to date. If Alto Maipo complies with the requirements of the Compliance Plan, and if the above-referenced lawsuits are dismissed, the Formulation of Charges will be discharged without penalty. Otherwise, Alto Maipo could be subject to penalties, and the construction of the project could be negatively impacted. Alto Maipo will pursue its interests vigorously in these matters; however, there can be no assurances that it will be successful in its efforts.

In June 2017, Alto Maipo terminated one of its contractors, Constructora Nuevo Maipo S.A. (“CNM”), given CNM’s stoppage of tunneling works, its failure to produce a completion plan, and its other breaches of contract. Also, Alto Maipo drew $73 million under letters of credit (“LC Funds”) in connection with its termination of CNM. Alto Maipo is pursuing arbitration against CNM to recover excess completion costs and other damages totaling over $230 million (net of the LC Funds) relating to CNM’s breaches (“First Arbitration”). CNM denies liability and seeks a declaration that its termination was wrongful, damages, and other relief. CNM has made submissions alleging that it is entitled to damages ranging from $70 million to $170 million (which include the LC Funds) plus interest and costs. Alto Maipo has contested these submissions. The evidentiary hearing in the First Arbitration is scheduled for May

46

20-31, 2019. Also, in August 2018, CNM purported to initiate a separate arbitration against AES Gener and the Company (“Second Arbitration”). In the Second Arbitration, CNM seeks to pierce Alto Maipo’s corporate veil and appears to seek an award holding AES Gener and the Company jointly and severally liable to pay any amounts that are found to be due to CNM in the First Arbitration or otherwise. The Second Arbitration has been consolidated into the First Arbitration. The arbitral Tribunal has bifurcated the Second Arbitration to determine in the first instance the jurisdictional objections raised by AES Gener and the Company to CNM’s piercing claims. A schedule is under development for the proceedings in the Second Arbitration. Each of the above-referenced AES companies believes it has meritorious claims and/or defenses and will pursue its interests vigorously; however, there can be no assurances that each of the AES companies will be successful in its efforts.

In October 2017, the Maritime Prosecution Office from Valparaíso issued a ruling alleging responsibility by AES Gener for the presence of coal waste on Ventanas beach, and proposed a fine before the Maritime Governor, of approximately $380,000. AES Gener submitted its statement of defense, denying the allegations. An evidentiary stage was concluded and then re-opened by order of the Maritime Governor on February 5, 2019 to allow AES Gener an opportunity to present reports and other evidence to challenge the grounds of the ruling. AES Gener believes that it has meritorious defenses to the allegations; however, there are no assurances that it will be successful in defending this action.

In February 2018, Tau Power B.V. and Altai Power LLP (collectively, “AES Claimants”) initiated arbitration against the Republic of Kazakhstan (“ROK”) for the ROK’s failure to pay approximately $75 million (“Return Transfer Payment”) for the return of two hydropower plants (“HPPs”) pursuant to a concession agreement. In April 2018, the ROK responded by denying liability and asserting purported counterclaims concerning the annual payment provisions in the concession agreement, a bonus allegedly due for the 1997 takeover of the HPPs, and dividends paid by the HPPs. The ROK seeks to recover the Return Transfer Payment (which is in an escrow account maintained by a third party) and appears to be seeking over $480 million on its counterclaims. The AES Claimants believe that the ROK’s defenses and counterclaims are without merit and have contested the ROK’s submissions on these issues. An arbitrator has been appointed to decide the case. The final evidentiary hearing is scheduled for July 22 - 26, 2019. The AES Claimants will pursue their case and assert their defenses vigorously; however, there can be no assurances that they will be successful in their efforts.

In December 2018, a lawsuit was filed in Dominican Republic civil court against the Company, AES Puerto Rico, and three other AES affiliates. The lawsuit purports to be brought on behalf of over 100 Dominican claimants, living and deceased, and appears to seek relief relating to CCRs that were delivered to the Dominican Republic in 2004. The lawsuit generally alleges that the CCRs caused personal injuries and deaths and demands $476 million in alleged damages. The lawsuit does not identify, or provide any supporting information concerning, the alleged injuries of the claimants individually. Nor does the lawsuit provide any information supporting the demand for damages or explaining how the quantum was derived. The relevant AES companies believe that they have meritorious defenses to the claims asserted against them and will defend themselves vigorously in this proceeding; however, there can be no assurances that they will be successful in their efforts.

In February 2019, a separate lawsuit was filed in Dominican Republic civil court against the Company, AES Puerto Rico, two other AES affiliates, and an unaffiliated company and its principal. The lawsuit purports to be brought on behalf of over 200 Dominican claimants, living and deceased, and appears to seek relief relating to CCRs that were delivered to the Dominican Republic in 2003 and 2004. The lawsuit generally alleges that the CCRs caused personal injuries and deaths and demands $900 million in alleged damages. The lawsuit does not identify, or provide any supporting information concerning, the alleged injuries of the claimants individually. Nor does the lawsuit provide any information supporting the demand for damages or explaining how the quantum was derived. The relevant AES companies believe that they have meritorious defenses to the claims asserted against them and will defend themselves vigorously in this proceeding; however, there can be no assurances that they will be successful in their efforts.

In March 2019, the Puerto Rico Department of Natural and Environmental Resources (“DNER”) issued an Administrative Order, as amended (collectively, the “DNER Order”), alleging that AES Puerto Rico, LP failed to comply with certain DNER requests for documents and information and that AES Puerto Rico has contaminated groundwater in excess of certain state and federal water quality standards. The DNER Order imposes a fine of $160,000. In April 2019, AES Puerto Rico timely filed its response to the DNER Order contesting the alleged violations and fine and also moved to dismiss the matter. AES Puerto Rico believes that it has meritorious defenses, but there are no assurances that it will be successful in defending this action.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

FINANCIAL STATEMENT PRESENTATION

FINANCIAL STATEMENT PRESENTATION

Consolidation — In this Quarterly Report the terms “AES,” “the Company,” “us” or “we” refer to the consolidated entity, including its subsidiaries and affiliates. The terms “The AES Corporation” or “the Parent Company” refer only to the publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates. Furthermore, VIEs in which the Company has a variable interest have been consolidated where the Company is the primary beneficiary. Investments in which the Company has the ability to exercise significant influence, but not control, are accounted for using the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

Interim Financial Presentation — The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income, changes in equity and cash flows. The results of operations for the three months ended March 31, 2019, are not necessarily indicative of expected results for the year ending December 31, 2019. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2018 audited consolidated financial statements and notes thereto, which are included in the 2018 Form 10-K filed with the SEC on February 26, 2019 (the “2018 Form 10-K”).

Cash, Cash Equivalents, and Restricted Cash — The following table provides a summary of cash, cash equivalents, and restricted cash amounts reported on the Condensed Consolidated Balance Sheet that reconcile to the total of such amounts as shown on the Condensed Consolidated Statements of Cash Flows (in millions):

	March 31, 2019		December 31, 2018
Cash and cash equivalents	$	1,426	$	1,166
Restricted cash	519		370
Debt service reserves and other deposits	430		467
Cash, Cash Equivalents, and Restricted Cash	$	2,375	$	2,003

New Accounting Pronouncements Adopted in 2019 — 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
2018-02, Income Statement — Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from AOCI	This amendment allows a reclassification of the stranded tax effects resulting from the implementation of the Tax Cuts and Jobs Act from AOCI to retained earnings at the election of the filer. Because this amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.	January 1, 2019	The Company has not elected to reclassify any amounts to retained earnings. The Company’s accounting policy for releasing the income tax effects from AOCI occurs on a portfolio basis.
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	The adoption of this standard resulted in a $4 million increase to retained earnings.

2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606)	ASC 606 was adopted by sPower on January 1, 2019. sPower was not required to adopt ASC 606 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. Under the previous revenue standard, the payment received by sPower for the transfer of Incentive Tax Credits related to projects was deferred and recognized in revenue over time. Under ASC 606, this payment is recognized at a point in time.	January 1, 2019	The adoption of this standard resulted in an $8 million increase to retained earnings attributable to the AES Corporation stockholders’ equity.
2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842)	See discussion of the ASU below.	January 1, 2019	See impact upon adoption of the standard below.

On January 1, 2019, the Company adopted ASC 842 Leases and its subsequent corresponding updates (“ASC 842”). Under this standard, lessees are required to recognize assets and liabilities for most leases on the balance sheet, 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 eliminates previous real estate-specific provisions.

Under ASC 842, fewer contracts contain a lease. However, due to the elimination of the real estate-specific guidance and changes to certain lessor classification criteria, more leases qualify as sales-type leases and direct financing leases. Under these two models, a lessor derecognizes the asset and recognizes a lease receivable. According to ASC 842, the lease receivable includes the fair value of the asset after the contract period, but does not include variable payments 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.

During the course of adopting ASC 842, the Company applied various practical expedients including:

• The package of practical expedients (applied to all leases) that allowed lessees and lessors not to reassess:

a. whether any expired or existing contracts are or contain leases,

b. lease classification for any expired or existing leases, and

c. whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842.

• The transition practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements, and

• The transition practical expedient for lessees that allowed businesses to not separate lease and non-lease components. The Company applied the practical expedient to all classes of underlying assets when valuing right-of-use assets and lease liabilities. Contracts where the Company is the lessor were separated between the lease and non-lease components.

The Company applied the modified retrospective method of adoption and elected 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 applied the transition provisions starting at the date of adoption. The cumulative effect of the adoption of ASC 842 on our January 1, 2019 Condensed Consolidated Balance Sheet was as follows (in millions):

Condensed Consolidated Balance Sheet	Balance at December 31, 2018		Adjustments Due to ASC 842		Balance at January 1, 2019
Assets
Other noncurrent assets	$	1,514	$	253	$	1,767
Liabilities
Accrued and other liabilities	962		27		989
Other noncurrent liabilities	2,723		226		2,949

The primary impact of adoption was due to the recognition of a right-of-use-asset and lease liability for an operating land lease in Panama associated with the Colon LNG power plant and regasification terminal.

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
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.

Asset Retirement Obligation (Notes)	3 Months Ended
	Mar. 31, 2019
Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligation Disclosure [Text Block]	During the three months ended March 31, 2019, the Company decreased the asset retirement obligation at DPL by $23 million, resulting in a reduction to Cost of Sales on the Condensed Consolidated Statement of Operations as the related plants are no longer in service. This decrease was due to reductions in estimated closure costs associated with ash ponds and landfills. The Company uses the cost approach to determine the initial value of 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. Subsequent downward revisions of ARO liabilities are discounted using the market-based rates that existed when the liability was initially recognized.

Fair Value Disclosures [Abstract]

FAIR VALUE

FAIR VALUE

The fair value of current financial assets and liabilities, debt service reserves and other deposits approximate their reported carrying amounts. The estimated fair values of the Company’s assets and liabilities have been determined using available market information. By virtue of these amounts being 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. For further information on our valuation techniques and policies, see Note 4—Fair Value in Item 8.—Financial Statements and Supplementary Data of our 2018 Form 10-K.

Recurring Measurements — The following table presents, by level within the fair value hierarchy, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis as of the dates indicated (in millions). For the Company’s investments in marketable debt securities, the security classes presented are determined based on the nature and risk of the security and are consistent with how the Company manages, monitors and measures its marketable securities:

Receivables [Abstract]

FINANCING RECEIVABLES

FINANCING RECEIVABLES

Receivables with contractual maturities of greater than one year are considered financing receivables. The Company’s financing receivables are primarily related to amended agreements or government resolutions that are due from CAMMESA, the administrator of the wholesale electricity market in Argentina. The following table presents financing receivables by country as of the dates indicated (in millions):

	March 31, 2019		December 31, 2018
Argentina	$	97	$	93
Other	13		23
Total	$	110	$	116

Argentina — Collection of the principal and interest on these receivables is subject to various business risks and uncertainties, including, but not limited to, the operation of power plants which generate cash for payments of

these receivables, regulatory changes that could impact the timing and amount of collections, and economic conditions in Argentina. The Company monitors these risks, including the credit ratings of the Argentine government, on a quarterly basis to assess the collectability of these receivables. The Company accrues interest on these receivables once the recognition criteria have been met. The Company’s collection estimates are based on assumptions that it believes to be reasonable, but are inherently uncertain. Actual future cash flows could differ from these estimates.

DEBT

Recourse Debt

In March 2018, the Company purchased via tender offers $671 million aggregate principal of its existing 5.50% senior unsecured notes due in 2024 and $29 million of its existing 5.50% senior unsecured notes due in 2025. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $44 million for the three months ended March 31, 2018.

In March 2018, the Company issued $500 million aggregate principal of 4.00% senior notes due in 2021 and $500 million of 4.50% senior notes due in 2023. The Company used the proceeds from these issuances to purchase via tender offer in full the $228 million balance of its 8.00% senior notes due in 2020 and the $690 million balance of its 7.375% senior notes due in 2021. As a result of these transactions, the Company recognized a loss on extinguishment of debt of $125 million for the three months ended March 31, 2018.

Non-Recourse Debt

During the three months ended March 31, 2019, the Company’s subsidiaries had the following significant debt transactions:

Subsidiary	Issuances		Repayments			Gain (Loss) on Extinguishment of Debt
Southland	$	161	$	—		$	—
Gener	550		(363		)	(10		)
Total	$	711	$	(363	)	$	(10	)

Non-Recourse Debt in Default — The current portion of non-recourse debt includes the following subsidiary debt in default as of March 31, 2019 (in millions).

Subsidiary	Primary Nature of Default	Debt in Default		Net Assets
AES Puerto Rico	Covenant	$	311	$	151
AES Ilumina (Puerto Rico)	Covenant	34		18
Total		$	345

The above defaults are not payment defaults. All of the subsidiary non-recourse debt defaults were triggered by failure to comply with covenants or other requirements contained in the non-recourse debt documents due to the bankruptcy of the offtaker.

The AES Corporation’s recourse debt agreements include cross-default clauses that will trigger if a subsidiary or group of subsidiaries for which the non-recourse debt is in default provides 20% or more of the Parent Company’s total cash distributions from businesses for the four most recently completed fiscal quarters. As of March 31, 2019, the Company had no defaults which resulted in or were at risk of triggering a cross-default under the recourse debt of the Parent Company. In the event the Parent Company is not in compliance with the financial covenants of its senior secured revolving credit facility, restricted payments will be limited to regular quarterly shareholder dividends at the then-prevailing rate. Payment defaults and bankruptcy defaults would preclude the making of any restricted payments.

Commitments and Contingencies Disclosure [Abstract]

CONTINGENCIES AND COMMITMENTS

COMMITMENTS AND CONTINGENCIES

Guarantees, Letters of Credit and Commitments — In connection with certain project financings, acquisitions and dispositions, power purchases and other agreements, the Parent Company has expressly undertaken limited obligations and commitments, most of which will only be effective or will be terminated upon the occurrence of future events. In the normal course of business, the Parent Company has entered into various agreements, mainly guarantees and letters of credit, to provide financial or performance assurance to third parties on behalf of AES businesses. These agreements are entered into primarily to support or enhance the creditworthiness otherwise achieved by a business on a stand-alone basis, thereby facilitating the availability of sufficient credit to accomplish their intended business purposes. Most of the contingent obligations relate to future performance commitments which the Company or its businesses expect to fulfill within the normal course of business. The expiration dates of these guarantees vary from less than one year to more than 16 years.

The following table summarizes the Parent Company’s contingent contractual obligations as of March 31, 2019. Amounts presented in the following table represent the Parent Company’s current undiscounted exposure to guarantees and the range of maximum undiscounted potential exposure. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees.

Contingent Contractual Obligations	Amount (in millions)		Number of Agreements	Maximum Exposure Range for Individual Agreements (in millions)
Guarantees and commitments	$	633	28	$0 — 157
Letters of credit under the unsecured credit facility	368		6	$1 — 247
Letters of credit under the senior secured credit facility	80		30	$0 — 32

_____________________________

⁽¹⁾  Excludes normal and customary representations and warranties in agreements for the sale of assets (including ownership in associated legal entities) where the associated risk is considered to be nominal.

During the three months ended March 31, 2019, the Company paid letter of credit fees ranging from 1% to 3% per annum on the outstanding amounts of letters of credit.

Contingencies

Environmental — The Company periodically reviews its obligations as they relate to compliance with environmental laws, including site restoration and remediation. For each period ended March 31, 2019 and December 31, 2018, the Company had recognized liabilities of $5 million for projected environmental remediation costs. Due to the uncertainties associated with environmental assessment and remediation activities, future costs of compliance or remediation could be higher or lower than the amount currently accrued. Moreover, where no liability has been recognized, it is reasonably possible that the Company may be required to incur remediation costs or make expenditures in amounts that could be material but could not be estimated as of March 31, 2019. In aggregate, the Company estimates the range of potential losses related to environmental matters, where estimable, to be up to $16 million. The amounts considered reasonably possible do not include amounts accrued as discussed above.

Litigation — The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company has recognized aggregate liabilities for all claims of approximately $55 million and $53 million as of March 31, 2019 and December 31, 2018, respectively. These amounts are reported on the Condensed Consolidated Balance Sheets within Accrued and other liabilities and Other noncurrent liabilities. A significant portion of these accrued liabilities relate to regulatory matters and commercial disputes in international jurisdictions. There can be no assurance that these accrued liabilities will be adequate to cover all existing and future claims or that we will have the liquidity to pay such claims as they arise.

Where no accrued liability has been recognized, it is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material but could not be estimated as of March 31, 2019. The material contingencies where a loss is reasonably possible primarily include disputes with offtakers, suppliers and EPC contractors; alleged breaches of contract; alleged violation of laws and regulations; income tax and non-income tax matters with tax authorities; and regulatory matters. In aggregate, the Company estimates the range of potential losses, where estimable, related to these reasonably possible material contingencies to be between $79 million and $439 million. The amounts considered reasonably possible do not include the amounts accrued, as discussed above. These material contingencies do not include income tax-related contingencies which are considered part of our uncertain tax positions.

Segment Reporting [Abstract]

SEGMENTS

SEGMENTS

The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs. Using the accounting guidance on segment reporting, the Company determined that its four operating segments are aligned with its four reportable segments corresponding to its SBUs.

Corporate and Other — The results of the Fluence and Simple Energy equity affiliates are included in “Corporate and Other.” Also included are the results of the AES self-insurance company and corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation.

The Company uses Adjusted PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures;

(d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company’s internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company’s results.

Revenue and Adjusted PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, charges for certain management fees, and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.

Contract Balances — The timing of revenue recognition, billings, and cash collections results in accounts receivable and contract liabilities. The contract liabilities from contracts with customers were $128 million and $109 million as of March 31, 2019 and December 31, 2018, respectively.

During the three months ended March 31, 2019 and 2018, we recognized revenue of $3 million and $22 million, respectively, that was included in the corresponding contract liability balance at the beginning of the periods.

A significant financing arrangement exists for our Mong Duong plant in Vietnam. The plant was constructed under a build, operate, and transfer contract and will be transferred to the Vietnamese government after the completion of a 25 year PPA. The performance obligation to construct the facility was substantially completed in 2015. Approximately $1.4 billion of contract consideration related to the construction, but not yet collected through the 25 year PPA, was reflected as a loan receivable as of March 31, 2019.

Remaining Performance Obligations — The transaction price allocated to remaining performance obligations represents future consideration for unsatisfied (or partially unsatisfied) performance obligations at the end of the reporting period. As of March 31, 2019, the aggregate amount of transaction price allocated to remaining performance obligations was $15 million, primarily consisting of fixed consideration for the sale of renewable energy credits (RECs) in long-term contracts in the U.S. We expect to recognize revenue on approximately one-fifth of the remaining performance obligations in 2019, with the remainder recognized thereafter.

For further information on our accounting policies concerning contract balances and remaining performance obligations, see Note 18—Revenue in Item 8.—Financial Statements and Supplementary Data of our 2018 Form 10-K.

Income Taxes [Abstract]

Income Tax Disclosure [Text Block]

INCOME TAXES

The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective tax rates for the three months ended March 31, 2019 and 2018 were 32% and 23%, respectively. The difference between the Company’s effective tax rates for the 2019 and 2018 periods and the U.S. statutory tax rate of 21% related primarily to U.S. taxes on foreign earnings, foreign tax rate differentials, the impacts of foreign currency fluctuations at certain foreign subsidiaries, and nondeductible expenses.

In the first quarter of 2019, the U.S. Treasury issued final regulations related to the one-time transition tax which further amended the guidance of the proposed regulations. As a result, we recorded $3 million of discrete tax expense in the first quarter.

In the first quarter of 2018, the Company completed the sale of its entire 51% equity interest in Masinloc, resulting in pre-tax gain of approximately $777 million. The sale resulted in approximately $155 million of discrete tax expense in the U.S. under the new GILTI provision, which subjects the earnings of foreign subsidiaries to current U.S. taxation to the extent those earnings exceed an allowable return. See Note 18—Held-for-Sale and Dispositions for details of the sale.

Earnings Per Share [Abstract]

EARNINGS PER SHARE

EARNINGS PER SHARE

Basic and diluted earnings per share are based on the weighted average number of shares of common stock and potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted earnings per share, includes the effects of dilutive RSUs and stock options. The effect of such potential common stock is computed using the treasury stock method.

The following table is a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation for income from continuing operations for the three months ended March 31, 2019 and 2018, where income represents the numerator and weighted average shares represent the denominator.

Three Months Ended March 31,	2019					2018
(in millions, except per share data)	Income		Shares	$ per Share		Income		Shares	$ per Share
BASIC EARNINGS PER SHARE
Income from continuing operations attributable to The AES Corporation common stockholders	$	154	663	$	0.23	$	685	661	$	1.04
EFFECT OF DILUTIVE SECURITIES

DILUTED EARNINGS PER SHARE	$	154	667	$	0.23	$	685	663	$	1.03

The calculation of diluted earnings per share excluded stock awards which would be anti-dilutive. The calculation of diluted earnings per share excluded 1 million and 6 million stock awards outstanding for the three months ended March 31, 2019 and 2018, respectively, that could potentially dilute basic earnings per share in the future.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]

New Accounting Pronouncements Adopted in 2019 — 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
2018-02, Income Statement — Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from AOCI	This amendment allows a reclassification of the stranded tax effects resulting from the implementation of the Tax Cuts and Jobs Act from AOCI to retained earnings at the election of the filer. Because this amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.	January 1, 2019	The Company has not elected to reclassify any amounts to retained earnings. The Company’s accounting policy for releasing the income tax effects from AOCI occurs on a portfolio basis.
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	The adoption of this standard resulted in a $4 million increase to retained earnings.

2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606)	ASC 606 was adopted by sPower on January 1, 2019. sPower was not required to adopt ASC 606 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. Under the previous revenue standard, the payment received by sPower for the transfer of Incentive Tax Credits related to projects was deferred and recognized in revenue over time. Under ASC 606, this payment is recognized at a point in time.	January 1, 2019	The adoption of this standard resulted in an $8 million increase to retained earnings attributable to the AES Corporation stockholders’ equity.
2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842)	See discussion of the ASU below.	January 1, 2019	See impact upon adoption of the standard below.

Consolidation

Consolidation — In this Quarterly Report the terms “AES,” “the Company,” “us” or “we” refer to the consolidated entity, including its subsidiaries and affiliates. The terms “The AES Corporation” or “the Parent Company” refer only to the publicly held holding company, The AES Corporation, excluding its subsidiaries and affiliates. Furthermore, VIEs in which the Company has a variable interest have been consolidated where the Company is the primary beneficiary. Investments in which the Company has the ability to exercise significant influence, but not control, are accounted for using the equity method of accounting. All intercompany transactions and balances have been eliminated in consolidation.

Basis of Presentation and Significant Accounting Policies [Text Block]

Interim Financial Presentation — The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with GAAP, as contained in the FASB ASC, for interim financial information and Article 10 of Regulation S-X issued by the SEC. Accordingly, they do not include all the information and footnotes required by GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, comprehensive income, changes in equity and cash flows. The results of operations for the three months ended March 31, 2019, are not necessarily indicative of expected results for the year ending December 31, 2019. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the 2018 audited consolidated financial statements and notes thereto, which are included in the 2018 Form 10-K filed with the SEC on February 26, 2019 (the “2018 Form 10-K”).

Commitments and Contingencies

Litigation — The Company is involved in certain claims, suits and legal proceedings in the normal course of business. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated.

Segment Reporting

The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs. Using the accounting guidance on segment reporting, the Company determined that its four operating segments are aligned with its four reportable segments corresponding to its SBUs.

Corporate and Other — The results of the Fluence and Simple Energy equity affiliates are included in “Corporate and Other.” Also included are the results of the AES self-insurance company and corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation.

The Company uses Adjusted PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures;

(d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company’s internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company’s results.

Revenue and Adjusted PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, charges for certain management fees, and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.

Lessee, Leases [Policy Text Block]

The package of practical expedients (applied to all leases) that allowed lessees and lessors not to reassess:

a. whether any expired or existing contracts are or contain leases,

b. lease classification for any expired or existing leases, and

c. whether initial direct costs for any expired or existing leases qualify for capitalization under ASC 842.

• The transition practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements, and

•

The transition practical expedient for lessees that allowed businesses to not separate lease and non-lease components. The Company applied the practical expedient to all classes of underlying assets when valuing right-of-use assets and lease liabilities. Contracts where the Company is the lessor were separated between the lease and non-lease components.

Separation of Lease and Nonlease Components [Policy Text Block]	Capacity payments are generally considered lease elements as they cover the majority of available output from a facility. The allocation of contract payments between the lease and non-lease elements is made at the inception of the lease.
Incremental Borrowing Rate [Policy Text Block]	As our leases do not provide an implicit rate, we use the subsidiaries’ incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments.

Segment Reporting [Abstract]

Segment Reporting

The segment reporting structure uses the Company’s management reporting structure as its foundation to reflect how the Company manages the businesses internally and is mainly organized by geographic regions, which provides a socio-political-economic understanding of our business. The management reporting structure is organized by four SBUs led by our President and Chief Executive Officer: US and Utilities, South America, MCAC, and Eurasia SBUs.

Corporate and Other — The results of the Fluence and Simple Energy equity affiliates are included in “Corporate and Other.” Also included are the results of the AES self-insurance company and corporate overhead costs which are not directly associated with the operations of our four reportable segments, and certain intercompany charges such as self-insurance premiums which are fully eliminated in consolidation.

The Company uses Adjusted PTC as its primary segment performance measure. Adjusted PTC, a non-GAAP measure, is defined by the Company as pre-tax income from continuing operations attributable to The AES Corporation excluding gains or losses of the consolidated entity due to (a) unrealized gains or losses related to derivative transactions and equity securities; (b) unrealized foreign currency gains or losses; (c) gains, losses, benefits and costs associated with dispositions and acquisitions of business interests, including early plant closures;

(d) losses due to impairments; (e) gains, losses and costs due to the early retirement of debt; and (f) costs directly associated with a major restructuring program, including, but not limited to, workforce reduction efforts, relocations, and office consolidation. Adjusted PTC also includes net equity in earnings of affiliates on an after-tax basis adjusted for the same gains or losses excluded from consolidated entities. The Company has concluded that Adjusted PTC better reflects the underlying business performance of the Company and is the most relevant measure considered in the Company’s internal evaluation of the financial performance of its segments. Additionally, given its large number of businesses and complexity, the Company concluded that Adjusted PTC is a more transparent measure that better assists investors in determining which businesses have the greatest impact on the Company’s results.

Revenue and Adjusted PTC are presented before inter-segment eliminations, which includes the effect of intercompany transactions with other segments except for interest, charges for certain management fees, and the write-off of intercompany balances, as applicable. All intra-segment activity has been eliminated within the segment. Inter-segment activity has been eliminated within the total consolidated results.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]

New Accounting Pronouncements Adopted in 2019 — 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
2018-02, Income Statement — Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from AOCI	This amendment allows a reclassification of the stranded tax effects resulting from the implementation of the Tax Cuts and Jobs Act from AOCI to retained earnings at the election of the filer. Because this amendment only relates to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.	January 1, 2019	The Company has not elected to reclassify any amounts to retained earnings. The Company’s accounting policy for releasing the income tax effects from AOCI occurs on a portfolio basis.
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	The adoption of this standard resulted in a $4 million increase to retained earnings.

2014-09, 2015-14, 2016-08, 2016-10, 2016-12, 2016-20, 2017-10, 2017-13, Revenue from Contracts with Customers (Topic 606)	ASC 606 was adopted by sPower on January 1, 2019. sPower was not required to adopt ASC 606 using the public adoption date, as sPower is an equity method investee that meets the definition of a public business entity only by virtue of the inclusion of its summarized financial information in the Company’s SEC filings. Under the previous revenue standard, the payment received by sPower for the transfer of Incentive Tax Credits related to projects was deferred and recognized in revenue over time. Under ASC 606, this payment is recognized at a point in time.	January 1, 2019	The adoption of this standard resulted in an $8 million increase to retained earnings attributable to the AES Corporation stockholders’ equity.
2016-02, 2018-01, 2018-10, 2018-11, 2018-20, 2019-01, Leases (Topic 842)	See discussion of the ASU below.	January 1, 2019	See impact upon adoption of the standard below.

New Accounting Standards Issued But Not Yet Effective
ASU Number and Name	Description	Date of Adoption	Effect on the financial statements upon adoption
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.
