Inventory Disclosure [Abstract]
Inventories	Note C – Inventories Inventories are carried at the lower of cost or market. For the Company’s U.K. refining and marketing operations reported as discontinued operations, the cost of crude oil and finished products is predominantly determined on the last-in, first-out (LIFO) method. The U.K. inventories are reported within Current assets held for sale on the Consolidated Balance Sheet. At March 31, 2014 and December 31, 2013, the carrying values of inventories under the LIFO method were $201.6 million and $268.6 million, respectively, less than such inventories would have been valued using the first-in, first-out (FIFO) method.

The entire disclosure for inventory. This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.
