(a)Our available-for-sale securities primarily relate to debt securities with maturities over the next ten years.
(b)Our investment, which is classified as an available-for-sale debt security, has been measured based on third-party investors’ recent or pending transactions in these securities, which are considered the best evidence of fair value. When this evidence is not available, we use other valuation techniques as appropriate and available. These valuation methodologies may include transactions in similar instruments, discounted cash flow techniques, third-party appraisals or industry multiples and public company comparable transactions.

Fair Value of Debt

As of March 31, 2023 and December 31, 2022, the carrying value of our debt was $15.4 billion and $15.0 billion. The estimated fair value of our debt was approximately $14.4 billion and $13.8 billion as of March 31, 2023 and December 31, 2022, respectively. The increase in the fair value of debt is primarily due to net borrowings of $337 million in 2023 and, to a lesser extent, changes in the current market rates of our senior notes.

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of the instruments, could realize in a current market exchange. The use of different assumptions or estimation methodologies could have a material effect on the estimated fair values. The fair value estimates are based on Level 2 inputs of the fair value hierarchy available as of March 31, 2023 and December 31, 2022. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.
