Fair Value Disclosures [Abstract]

Assets and Liabilities Measured at Fair Value

NOTE 6 — ASSETS AND LIABILITIES MEASURED AT FAIR VALUE

Accounting Standards Codification 820, Fair Value Measurements and Disclosures (“ASC 820”), emphasizes fair value is a market-based measurement, and fair value measurements should be determined based on the assumptions market participants would use in pricing assets or liabilities. ASC 820 utilizes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment.

Investment Securities

The investments of our insurance subsidiaries are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.

Derivative Financial Instrument

We have entered into an interest rate swap agreement to manage our exposure to fluctuations in interest rates. The valuation of this instrument is determined using widely accepted valuation techniques, including a discounted expected cash flow analysis.

The following tables summarize our assets and liabilities measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021, aggregated by the level in the fair value hierarchy within which those measurements fall (dollars in millions):

The estimated fair value of our debt was $36.652 billion and $38.541 billion at June 30, 2022 and December 31, 2021, respectively, compared to carrying amounts, excluding debt issuance costs and discounts, aggregating $39.219 billion and $34.827 billion, respectively. The estimates of fair value are generally based upon the quoted market prices or quoted market prices for similar issues of debt with the same maturities.
