Fair Value

9 Months Ended

Sep. 30, 2018

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 2017 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:

As of September 30, 2018, all AFS debt securities had stated maturities within one year. For the three and nine months ended September 30, 2018 and 2017, no other-than-temporary impairments of marketable securities were recognized in earnings or Other Comprehensive Income. Gains and losses on the sale of investments are determined using the specific-identification method. The following table presents gross proceeds from the sale of AFS securities during the periods indicated (in millions):

The following tables present a reconciliation of net derivative assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and nine months ended September 30, 2018 and 2017 (presented net by type of derivative in millions). Transfers between Level 3 and Level 2 are determined as of the end of the reporting period and principally result from changes in the significance of unobservable inputs used to calculate the credit valuation adjustment.

The following table summarizes the significant unobservable inputs used for Level 3 derivative assets (liabilities) as of September 30, 2018 (in millions, except range amounts):



Type of Derivative	Fair Value			Unobservable Input	Amount or Range (Weighted Average)
Interest rate	$	(96	)	Subsidiaries’ credit spreads	1.78% to 4.38% (3.63%)
Foreign currency:
Argentine Peso	221			Argentine peso to USD currency exchange rate after one year	42.08 to 166.5 (99.21)
Commodity:
Other	8
Total	$	133

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.

Nonrecurring Measurements

The Company measures fair value using the applicable fair value measurement guidance. Impairment expense is measured by comparing the fair value at the evaluation date to the then-latest available carrying amount. The following table summarizes our major categories of assets measured at fair value on a nonrecurring basis and their level within the fair value hierarchy (in millions):



	Measurement Date	Carrying Amount (1)		Fair Value						Pretax Loss
Nine months ended September 30, 2018	Measurement Date	Carrying Amount (1)		Level 1		Level 2		Level 3		Pretax Loss
Equity Method Investments

⁽¹⁾	Represents the carrying values at the dates of initial measurement, before fair value adjustment.


⁽²⁾	See Note 14—Asset Impairment Expense for further information.


⁽³⁾	Per the Company’s policy, pretax loss is limited to the impairment of long-lived assets. Any additional loss will be recognized on completion of the sale. See Note 17—Held-for-Sale and Dispositions for further information.

When determining the fair value of the U.S. generation facility’s long-lived assets, the Company used the market approach based on prices and unobservable inputs from transactions involving comparable assets as the inputs for the Level 3 nonrecurring measurement.

Asset Retirement Obligation — During the nine months ended September 30, 2018, the Company increased the asset retirement obligation at IPL by $53 million. This increase was due to ash pond closure costs and revised closure dates associated with an EPA rule regulating CCR and additional coal pile remediation costs. The Company uses the cost approach to determine the fair 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. These inputs to the fair value of the ARO liabilities would be considered Level 3 inputs under the fair value hierarchy.

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

The following table presents (in millions) the carrying amount, fair value and fair value hierarchy of the Company’s financial assets and liabilities that are not measured at fair value in the Condensed Consolidated Balance Sheets as of September 30, 2018 and December 31, 2017, but for which fair value is disclosed:

Assets:	Accounts receivable — noncurrent ⁽¹⁾	$	105	$	224	$	—	$	—	$	224
Liabilities:	Non-recourse debt	15,581		15,429		—		12,699		2,730
	Recourse debt	3,820		3,901		—		3,901		—

These amounts primarily relate to amounts due from CAMMESA, the administrator of the wholesale electricity market in Argentina, and are included in Other noncurrent assets in the accompanying Condensed Consolidated Balance Sheets. The fair value and carrying amount of these receivables exclude VAT of $14 million and $31 million as of September 30, 2018 and December 31, 2017, respectively.
