The Company produces oil and natural gas in the United States, Canada and Malaysia and conducts oil and natural gas exploration activities worldwide. The Company has an interest in a Canadian synthetic oil operation. Murphy owns one petroleum refinery in the United Kingdom and markets petroleum products in that country under various brand names and to unbranded wholesale customers. The Company has announced its intention to sell the U.K. refining and marketing assets. On August 30, 2013, the Company completed the spin-off of Murphy USA Inc. (MUSA) to its shareholders. MUSA formerly was the Company’s U.S. downstream operations. MUSA is now a separate, publicly owned company traded on the New York Stock Exchange under the symbol “MUSA.” In addition, Murphy Oil sold all its United Kingdom oil and natural gas producing assets during 2013. In 2011, the Company sold two U.S. petroleum refineries and certain associated marketing assets. See Note C regarding more information regarding the spin-off and sale of these assets.</font></p> </div>
