Inventory Disclosure [Abstract]

Inventories

(4) Inventories

Inventories consisted of the following:

(in millions)			March 31, 2020						December 31, 2019
Raw materials			$	61					$	112
In-process inventories			10						18
Finished goods			77						177
Parts, supplies and other			63						66
Total inventories			$	211					$	373

The carrying amounts of the Petroleum Segment’s inventories exceeded their net realizable value (market value) by $58 million resulting in the recognition of a lower of cost or net realizable value adjustment as of March 31, 2020. The $58 million loss represents the difference between the carrying value of the Petroleum Segment’s inventories accounted for using the first-in-first-out method and selling prices for refined products subsequent to March 31, 2020. No adjustment was necessary as of December 31, 2019.
