⁽¹⁾We classified these commercial paper notes and credit facility borrowings as short-term as of December 31, 2019, as these notes and borrowings were primarily designated as working capital borrowings, were required to be repaid within one year and were primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.

⁽²⁾During the six months ended June 30, 2020, we repurchased $17 million of our outstanding senior notes on the open market and recognized a gain of $3 million on these transactions, which is included in “Other income/(expense), net” on our Condensed Consolidated Statement of Operations.

(3)Our fixed-rate senior notes had a face value of approximately $9.7 billion and $9.0 billion as of June 30, 2020 and December 31, 2019, respectively. We estimated the aggregate fair value of these notes as of June 30, 2020 and December 31, 2019 to be approximately $9.7 billion and $9.3 billion, respectively. Our fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near the end of the reporting period. We estimate that the carrying value of outstanding borrowings under our credit facilities, commercial paper program and GO Zone term loans approximates fair value as interest rates reflect current market rates. The fair value estimates for our senior notes, credit facilities, commercial paper program and GO Zone term loans are based upon observable market data and are classified in Level 2 of the fair value hierarchy.
