Fair Value

6 Months Ended

Jun. 30, 2019

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:

As of June 30, 2019, all AFS debt securities had stated maturities within one year. For the three and six months ended June 30, 2019 and 2018, 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):



	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Gross proceeds from sale of AFS securities	$	176	$	267	$	324	$	414

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 six months ended June 30, 2019 and 2018 (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 June 30, 2019 (in millions, except range amounts):



Type of Derivative	Fair Value			Unobservable Input	Amount or Range (Weighted Average)
Interest rate	$	(243	)	Subsidiaries’ credit spreads	1.78% - 4.38% (3.9%)
Foreign currency:
Argentine peso	192			Argentine peso to U.S. dollar currency exchange rate after one year	56 - 202 (130)
Commodity:
Other	4
Total	$	(47	)

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						Pre-tax Loss
Six Months Ended June 30, 2019	Measurement Date	Carrying Amount (1)		Level 1		Level 2		Level 3		Pre-tax Loss
